Advanced Restore - Linux File System

Performing an Out-of-Place Restore

You can restore the data to following locations:

  • Different folder on the same computer from which the data was backed up

  • Different computer

Keep in mind that the destination computer must reside in the same CommCell as the client whose data was backed up.

Restoring to a Different Folder on the Same Client

Follow the steps given below to restore data to a different folder on the same client from which data is backed up:

  1. From the CommCell Browser, navigate to Client Computers > client > File System backupset.

  2. Right-click the Subclient in the right pane and then click Browse and Restore.

  3. Click View Content.

  4. Select the data that you want to restore and click Recover All Selected.

  5. Clear the Restore to same folder check box and click Browse.

  6. Click OK.

  7. Use the options in the Preserve Source Paths area to exclude folders (and its contents) from the source path.

    For Example: If the selected data is /Documents/Memos/Sales, and you want to restore data only from the Sales folder, set the Preserve <n> level from end of source path option to 1.

    If the selected data is /Documents/Memos/Sales, and you want to restore the data from Memos and Sales folders, set the Remove <n> level from beginning of source path option to 2.

  8. Click OK.

Restoring Data to a Different Client
Procedure

  1. From the CommCell Browser, expand to Client Computers > client > File System > backupset.

  2. In the right pane, right-click a subclient, and click Browse and Restore.

  3. In the Browse and Restore dialog box, click View Content.

  4. Select the data that you want to restore, and click Recover All Selected.

  5. On the Restore Options - General tab:

    1. In the Destination Client list, select a client in the same CommCell as the client from which the data was backed up.

    2. Clear the Restore to same folder check box.

    3. In the Specify Destination Path box, enter the path on the destination client. Optionally, click Browse and in the Browsing for destination folder on client dialog box, select the destination folder and click OK.

      Important: Enter the path in Specify Destination Path box even if you are restoring to the same folder on the destination client.

  6. When you are satisfied with your selections, click OK.

Result

Once the restore is complete, the data is restored to the destination folder you specified in the Restore Options dialog box. If the folder you specified does not exist, a folder with the same name is created and the data is restored to that folder.

Performing a Cross-Platform Restore

You can perform the following cross-platform restores :

  • Restores across all the supported versions of Unix.

  • Restores from Unix to all the supported versions of Windows.

Follow the steps given below to perform a cross-platform restore:

  1. From the CommCell Browser, navigate to Client Computers > client > File System backupset.

  2. Right-click the Subclient in the right pane and then click Browse and Restore.

  3. Click View Content.

  4. Select the data that you want to restore and click Recover All Selected.

  6. In the Destination Client list, select the client. You can select any client that is in the same CommCell as that of the client from which the data was backed up.

  7. Click Browse to select the destination folder and click OK.

  8. Click OK.

Ignoring Errors When Restoring From or To an NFS Mount

During restore operations, errors are reported by the chown system call especially when the source or destination is an NFS mount and because changing file ownership as a root user is not allowed by the NFS server.

By default, such errors must be ignored manually to continue with the restore operation. However, you can choose to ignore such errors using the following steps:

  1. From the CommCell Browser, navigate to Client Computers.

  2. Right-click the <Client> in which you wish to perform the restore, and then click Properties.

  3. Click Advanced and then click Additional Settings tab.

  4. Click Add.

  5. In the Name field, type ignoreChownErrors.

    The Category and Type fields are populated automatically.

  6. In the Value field, type:

    1 - to ignore EINVAL error

    2 - to ignore any error reported by chown

  7. Click OK.

Using Multiple Streams to Restore Data with the Linux File System Agent

By default, restore operation uses a single stream. For faster restore operations, you can configure the restore operation to use multiple streams, and you can define alternate data paths. For more information, see GridStor® (Alternate Data Paths) - Overview.

Notes: You cannot use multiple streams for restore operations on clients with only File System Core package installed (Laptop Backup clients).

Before You Begin

  • Verify that you have v11 Service Pack 6 or later installed on the source client computers and on the destination client computers.

  • Verify that the client computer whose data you want to restore was backed up using Indexing Version 2. For more information about Indexing Version 2, see Indexing Version 2: Overview.

  • For more information about general restore options, see Restore/Recover Options (General).

  • For more information about the Advanced Options, see Advanced Restore Options.

Procedure

  1. From the CommCell Console, expand Client Computers > client > File System > backup set.

  2. In the right pane, right-click a subclient, and then click Browse and Restore.

    The Browse and Restore Options dialog box appears.

  3. Click View Content.

  4. Select the data that you want to restore, and then click Recover All Selected.

    The Restore Options dialog box appears.

  5. On the General tab, complete the following steps:

    1. In the Destination Client list, select the destination client computer.

    2. In the Number of Streams box, enter the recommended number of data streams that you want to use for the restore operation.

      Notes:

      • The actual number of streams used depends on the restore data set and the number of streams used to back up data.

      • When you perform a restore by jobs operation, the Number of Streams option is not available because restore by job operations use multiple streams by default.

  6. On the Job Initiation tab, choose how you want to initiate the restore jobs.

    For more information about job initiation options, see Restore Options (Job Initiation).

  7. Click OK.

Result

The restore operation restores the selected data to the destination client computer.

Using Multiple Nodes to Restore Data to NFS-Mounted File System with the Linux File System Agent

By default, restore operation uses a single node when you perform restores to NFS-mounted file systems. For faster restore operations, you can configure the restore operation to use multiple nodes, and you can define alternate data paths. For more information, see GridStor® (Alternate Data Paths) - Overview.

If you want to perform restores to distributed file systems or to network file systems such as NFS-mounted file systems that are mounted across multiple computers, use multiple nodes.

Notes: You cannot use multiple nodes for restore operations on clients with only File System Core package installed (Laptop Backup clients).

Before You Begin

  • Verify that you have v11 Service Pack 7 or later installed on the source client computers and on the destination client computers.

  • Verify that the client computer whose data you want to restore was backed up using Indexing Version 2. For more information about Indexing Version 2, see Indexing Version 2: Overview.

  • For more information about general restore options, see Restore/Recover Options (General).

  7. Click OK.

    Note

    Clear the Overwrite Files check box when restoring to a computer that has different hardware and different software device drivers.

Restoring Only When Data Exists on the Destination

Follow the steps given below to restore the only data that already exists in the destination computer. This ensures any data removed from the destination computer is not reintroduced by the data recovery.

  1. From the CommCell Browser, navigate to Client Computers > client > File System backupset.

  2. Right-click the Subclient in the right pane and then click Browse and Restore.

  3. Click View Content.

  4. Select the data that you want to restore and click Recover All Selected.

  6. From the Destination Client list, select the destination client.

  7. Click Browse to select a destination directory.

  8. Click OK.

  9. Select the Impersonate User check box and type the user account details for impersonation:

    • User Name

    • Password

    • Confirm Password

      You must have the necessary privileges to write to the destination directory.

  10. Click OK.

The user name and password are verified on the destination client before a user is impersonated.

The restore job goes into a pending state if the verification fails. On successful verification, data is restored if the impersonated user has the following permissions:

In-Place Restore

Out-of-Place Restore

If the file exists in the restore destination

  • If the file belongs to the user, the user must have write permission to the file irrespective of write permissions to the group and other users.

  • If the file belongs to the group of the user but is not owned by the user, then the group must have write permissions to the file; the file modified time is not preserved in this case.

  • If the file does not belong to either the user or the group, then other users must have write permissions to the file; the file modified time is not preserved in this case.

  • If the file does not belong to the user, ACLs (Access Control Lists) are supported.

Write permission to the destination folder, including the following additional permissions-

  • If the file belongs to the user, the user must have write permission to the file irrespective of write permissions to the group and other users.

  • If the file belongs to the group of the user but is not owned by the user, then the group must have write permissions to the file; the file modified time is not preserved in this case.

  • If the file does not belong to either the user or the group, then other users must have write permissions to the file; the file modified time is not preserved in this case.

  • If the file does not belong to the user, ACLs (Access Control Lists) are supported.

If the file does not exist in the restore destination

Write permission to the destination folder, including read permission on the backed up file, or the user must have file ownership.

Write permission to the destination folder, including Read permission on the backed up file, or the user must have file ownership.

Restores Using End-User Access Permission

You can perform restores using the End-User Access permission by impersonating users, from either the CommCell Console or the command-line interface.

If you are using the CommCell Console, you must set the Impersonate User option.

If you are using the command-line interface, UNIX user ID (UID) is used for impersonation. The UID is the ID of the user who is logged on the UNIX system. The default UID value for the root user is zero.

Before You Begin

  1. Set the EnforceUnixUserPermissionsOnRestore additional setting to 1 on the CommServe. For instructions on adding the additional setting, see Adding or Modifying Additional Settings from the CommCell Console.

  2. Verify that you have one of the following permissions for performing a restore:

    Type of restore

    Permissions required

    In-place

    • A CommCell user having the Browse and End-User Access permissions, and any one of the following:

      • User UID. (The UID is automatically populated only for command-line restores)

      • Impersonation enabled

    Out-of-place, same computer

    • A CommCell user having the Browse and End-User Access permissions, out-of-place permission on the client, and any one of the following:

      • User UID

      • Impersonation enabled

    Out-of-place, cross-computer (only UNIX to UNIX)

    • A CommCell user having the Browse and End-User Access permissions with the following:

      • Impersonation enabled and out-of-place permission on the source client

Performing Restores Using End-User Access Permission From the CommCell Console

You can perform restores using the End-User Access permission by setting the Impersonate User option from the CommCell Console. For instructions on setting the Impersonate User option, see Restores Using User Impersonation.

Performing Restores Using End-User Access Permission From the Command Line

If you perform restores using the End-User Access permission from the command-line, the UID of the user running the QCommand is used for impersonation.

By using the Save As Script option in the CommCell Console, you can save the restore options on the source client to an XML script. The QCommand uses the XML script to perform the restores. QCommand determines the UID which will be used for impersonating the restores. For details about the permissions required by the impersonating user, see Restores Using User Impersonation.

For instructions on how to perform a command-line restore, see Command Line Restore - UNIX and Linux File Systems.

Important Considerations

Review these important considerations before you perform a restore using the End-User Access permission:

  • If the Impersonate User option is not set in the XML script, then the UID of the user running the QCommand is used for impersonation. Cross-computer restores are not supported in this case.

  • If the Impersonate User option is set in the XML script, then that user account is used for impersonation. The impersonation XML tag takes precedence over the user UID.

  • Restores using the End-User Access permission are not supported for non-root client installations.

  • Pre-restore and post-restore commands are not supported.

  • On the HP-UX system, the user who owns a file can change the ownership of the file for any other user on the computer. To improve the efficiency of the restores using the End-User Access permission, disable this default setting.

Procedure

  1. Log on to the HP-UX destination computer as a root user.

  2. Use a text editor to open the /etc/privgroup file, or create the file if necessary.

  3. Add or edit the following line, and save the file. 

    -n CHOWN

  4. At the UNIX shell prompt, run the following command: 

    setprivgrp -f /etc/privgroup

  5. Log on again as root user.

  6. Restart Commvault services.

Restoring by Jobs

You can select a specific backup job for a restore. This method of restoring data is faster and useful in the following scenarios:

  • To restore point-in-time data associated with a specific backup job

  • To restore multiplexed data from the same client

You can specify the number of source path levels to strip when restoring a specific job by using the Command Line Interface.

If you do not want to restore the operating system files or directories, avoid restoring a specific job when it is associated with the default backup set. The entire content of the backed up client will be restored and the client where you are restoring might run out of space.

Restores by jobs use the same number of streams that you configured for the subclient. For more information on configuring multiple streams for subclients, see Configuring Multiple Streams for Backups.

filter_paths

Supported Wildcards in Filters

The following wildcards can be used in filters to exclude data when restoring data.

Wildcards

Description

Examples

*

Any number of characters. This wildcard is used in the following scenarios:

  • Filter all files of a specific extension

  • Filter all files under a specific directory

  • Filter all files of a specific extension where the file name starts with a specific pattern.

  • *.doc filters all files with the extension .doc, for example "status.doc" and "mission.doc," on all partitions on the client computer.

    /Test/*.doc filters all .doc files only in the /Test directory.

  • a*.so filters all files with the extension .so, for example "alsvc.so" and "advdcc.so" on the client computer which have the name beginning with "a".

  • /Finance/Test/* filters all the files and directories in the "Test" directory under the "Finance" directory on the / partition. Any sub-directories under the Test directory are not get backed up.

?

Any one character.

  • This wildcard can be used in the following scenario:

  • All files (or directories) for which any one character in the file name or the directory name is variable.

  • /access? filters any directory or file on the machine for which the name begins with- "access" followed by any one character such as "access1" or "access5". However, "access12" or "access15" are not backed up because the last two characters in the name are variable.

  • /Class/report? filters any directory or file under the /Class directory where the character in place of the question mark (?) is variable. For example: "/Class/report1" and "/Class/report2" are backed up. However, "/Class/report15" is not backed up.

[]

Set or range of characters.

  • /[a-m]*.doc filters any file with .doc extension on the / partition for which the name begins with the letters "a" through "m”.

  • /[AEIOU]*.doc filters any file name that ends with .doc and begins with the letters A, E, I, O, or U.

  • /Finance/report[1-47-9] filters files report1, report2, report4, report7, report8, report9 under the Finance directory.

  • /Department-[A-CS] filters files Department-A, Department-B, Department-C, and Department-S.

[!]

The negation of a set or range of characters. You can use the wildcard in the following scenario: filter all files in a directory except the files for which the name starts with any character from the specified set or range of characters.

/root/[!AEIOU]*.doc filters all .doc files in the /root directory that start with a letter other than A, E, I, O, or U.

**

Matches any directory level.

  • /**/move.cpp filters the file named move.cpp located at any directory level. For example: /root/newapp/move.cpp/opt/kde3/src/move.cpp.

  • /etc/** filters all directories, sub-directories, and files under the /etc directory.

***

Matches any directory level, including the parent directory

  • /etc/*** filters all directories, sub-directories, and files under the /etc directory, and the /etc directory itself.

  • To filter all directories, sub-directories, and files under the /etc directory, specifying /etc/*** instead of /etc/** improves performance because /etc/*** filters the /etc directory itself. This is especially useful if you have a large subset of the file system under the /etc directory.

Notes:

  • When you use wildcards to specify the subclient content, the content path appears in Italics.

  • If you want all the files with the file extension ".doc" to be filtered from any level, then specify the content as "*.doc". If any subclient content does not start with a forward slash (/), then "/**/" will be prefixed to the content to match at any level. For example: "*.doc" will become "/**/*.doc".

  • If you wants to treat the asterisk (*), question mark (?), and square brackets ([ ]) as literal, and not as wildcards, then add a forward slash (\) before the wildcard. For example: /Report\[2011-2012\]/*.doc will filter all the .doc files under /Report[2011-2012]

  • More than one type of wildcard can be used when specifying subclient content. For example: /Dcvol?/oracle[1-47]/**/*.log).

Restoring Mixed Mode Data

In addition to specifying the data to be restored using the wildcard expressions, you can also select specific data to restore. This is known as a mixed mode restore. Both the selected data as well as the data that satisfies the wildcard expression(s) is restored, with one important exception. All directories that are to be restored, whether they were specifically named or selected, or merely satisfy the wildcard expression(s) are restored without their content. That is, any directory to be restored is handled in the same way as if the directory was being restored as a result of a wildcard expression.

Use the following steps to perform a mixed mode restore:

  1. From the CommCell Browser, navigate to Client Computers | Client | File System | Backup Set.

  2. Right-click the Subclient in the right pane and then click Browse and Restore.

  3. From the Restore Options dialog box, click the Filter tab.

  4. Select Add from Filter Criteria and choose File Name filter. Use wildcards to match specific file name patterns.

    Note

    If more than one filter is used in the browse request, the objects qualifying all the filters will be displayed in the browse results.

  5. Click View Content.

Restoring Data Using a Map File

You can restore individual files and folders to different locations using a map file containing a list of files to be restored, with their corresponding restore paths.

Creating a Map File

The map file is a text file in the CSV (Comma Separated Value) format. Follow the steps given below to create a map file:

  1. Create a text file on the client computer where you want to restore the data.

  2. Add the mapping information in the file in the following format:

    "<source path>","<destination path>"

If the specified destination folder is not available, the necessary destination folder will be created during the restore.

The specified paths for both the source and destination should be absolute paths within the same client computer.

You can provide following information in a map file:

Information

Example

File to File Mapping

"/dir1/file1.txt","/dir2/file1.txt"

Folder to folder mappings

"/dir2/info/","/dir4/info/"

Drive to drive mappings

"/"(root),"/mnt","/usr"

Rename files/folder during restore

"/dir4/file2.txt","/dir5/file3.txt"

Filter certain files

"/dir5",""

Adding Files and Folders with Unicode Characters to a Map File

If the path or the filename contains Unicode characters, the Map File must be converted to a format that can be used by the data protection operation. The Unicode Conversion utility must be used to convert the Map File to a format that can be provided as input.

  1. Using a text editor, create a file that contains a list of files or folders with Unicode characters and save the file as a Unicode text file.

  2. From the command line, navigate to the <software install folder>/Base folder and type the following: 

     
    ./CVconvertUnicode <source file> <destination file>

    where:

    • <source file> is the full path and name of the file created in Step 1.

    • <destination file> is the full path and name of the destination file. This file is automatically created by the utility.

  3. Use the destination file as the Map File to perform the restore.

Partial File Restore Using a Map File

Files can be restored partially using a Map file. Multiple files can be added in the Map file for partial restores with specific start/ stop offset values. These restores can be run from the CommCell GUI or from the command line. Partial file restores are supported for:

  • Index restores

  • Index Free Restore – Restore By Job

  • Using a text editor, create a text file on the client computer where you want to restore the data.

  • Add the mapping information in the file using the following syntax:

    “<source file path>”,“<destination file path>”,<start offset>,<stop offset>

    Where:

    <start offset> and <stop offset> are values in bytes

    For example: “/path1/data1/SRC”,"/path2/data2/DEST”,100,1000

The partial file restore behavior with different mapping options is given below:

Mapping

Behavior

File in map, no start offset and no stop offset

File will be restored fully

File in map, only start offset provided

File will be restored from <start offset> till the end of the file

File in map, start and stop offsets provided

File will be restored from <start offset> to <stop offset>

File in map, start offset provided in invalid format (not a number)

Restore will start from the beginning of the file

File in map, stop offset provided in invalid format (not a number)

Restores till the end of the file

File in map, stop offset value is less than start offset

Restores till the end of the file

Map file having duplicate source file entry with different destination location

Only the first source file entry will be honored

Map file with folder path, start and stop offsets provided

All the files under the folder will honor the start and stop offsets
