System Requirements for 1-Touch for Windows

The following are the requirements for 1-Touch on Windows:

Client

Hard Drive

7 GB minimum of hard disk space for installing the software.

500 MB of free disk space is required for job result directory.

500 MB of free disk space is required for log directory.

The RAM size of the client must be two times the size of the Live CD. The size of the Live CD can vary depending on the processor type and drivers added to the image. The default size is approximately 1 GB.

To perform an offline restore, make sure that you have an additional 30 GB of free disk space that includes the Job Results and Log files directory.

Processor

All Windows-compatible processors are supported.

Notes

Recovery Considerations

• Obtain the valid Microsoft license key for the Windows operating system to perform 1-Touch recovery operations.

• Ensure that Windows is not installed on the drive other than C:\. The unattended installation of Windows on a drive other than C:\ is not supported. You cannot perform the Online or Offline Restore when Windows is installed on a drive other than C:\.

• 1-Touch does not support recovery for multiboot systems.

• 1-Touch does not support recovery of disks managed by Veritas Volume Manager due to inconsistent results with VDS.

• 1-Touch recovery operations are not supported for system drive on GPT dynamic disk.

• 1-Touch recovery operations are not supported on a client with multiple instances.

• Restores are not supported for Resilient File Systems (Refs) and Storage Pools that operate on Microsoft Windows 2012 or Windows 8.0.

• You must use a wired internet connection to recover a laptop.

• You cannot restore mount points using 1-Touch recovery operations.

• During a 1-Touch recovery operation, a dynamic disk is converted to a basic disk and is recovered as a basic disk. You must manually bring the dynamic disk back online after the operation completes.

Recovery Support

• 1-Touch recovery operations are not supported for USB disks. By default, system state backups do not back up the content in USB disks.

• 1-Touch recovery operations are supported for NVMe (non-volatile memory express) disks.

• 1-Touch support recovery of BitLocker Encryption enabled volumes with lock opened during backup; post restore this option is disabled and you need to manually enable the BitLocker Encryption option on the volumes.

• 1-Touch recovery operations are supported for systems which boot from SAN or the recovery of SAN attached disks.

• If the client computer has more than 100 disks attached, then the system drive is restored initially, and then the other drives and data are restored later.

• Use 1-Touch interactive recovery to restore a MediaAgent computer. You cannot use 1-Touch non-interactive restore operations to restore a MediaAgent computer.

Partitions

• Ensure that the client does not have multiple active partitions. You cannot perform 1-Touch recovery operations if the client has multiple active partitions.

• If you have a recovery partition, make sure that it is removed prior to a backup operation.

Network and Protocols

• Ensure that the TCP/IP Services are configured on the computer before performing the backup.

• IPv6 is not supported for 1-Touch recovery of clients.

• NIC teaming is retained only if the restore operation is performed to the same computer. After a 1-Touch recovery operation to a dissimilar computer, the NIC teaming configuration will not be maintained.

• 1-Touch recovery operations are not supported for VLAN (Virtual Local Area Network) configurations where the NIC (Network Interface Control) is configured with VLAN tagging.
