Hard Drive

2 GB of free disk space is required for the /tmp directory.

No additional disk space required beyond File System Agent disk space requirements.

Memory (RAM)

8 GB, or minimum memory requirements of the applications running on the server, whichever is greater.

Processor

  • x86

  • x64

  • Compatible processors

Peripherals

A CD-ROM drive or ability to boot from an ISO image file is required to boot the client for recovery.

Operating System Utilities

For a list of operating system utilities required for 1-Touch, see FAQs - Operating system utilities to perform 1-Touch recovery.

Bootloader

Supported file system and volume manager types

  • Linux Logical Volume Manager (LVM) Version 2

    ~Unencrypted LVMs are supported. Thin volumes are not supported.~

  • B-tree File System (Btrfs)

    ~Only 1-Touch recovery on similar systems and Virtualize Me are supported.~

  • Second Extended File System (ext2)

  • Third Extended File System (ext3)

  • Fourth Extended File System (ext4)

  • Reiser File System (reiserfs)

  • XFS

Note

Snapshot volumes will not be recovered as part of the 1-touch recovery. Hence, it is recommended that you mount and back up the snapshot data.

Supported VMs

  • VMware

  • Microsoft Hyper-V*

  • Oracle VM**

  • Kernel-based VM for Linux (KVM)

    KVM on OpenStack is not supported.

  • Citrix Xen guest VM**

*Host operating system version of Microsoft Windows Server 2012 R2 Editions or higher **For Oracle VM and Citrix Xen guest VM, perform recovery using the 1-Touch for Linux - Single-Stage DVD procedure. For information, see 1-Touch for Linux - Single-Stage DVD. **For in-place restores of Citrix Xen guest VMs or for restores to another VM running on Citrix Xen, perform recovery using the 1-Touch for Linux - Single-Stage DVD procedure. For information, see 1-Touch for Linux - Single-Stage DVD. **To migrate Citrix Xen guest VMs to a non-Citrix Xen environment, see Migrating Citrix Xen Guest VMs to Another Hypervisor or Physical Host.

Notes

CommServe

  • To enable 1-Touch recovery, the Force per-client certificate authentication on CommServe option has to be turned off on the CommServe at least for the duration of the recovery. This option can be accessed from the CommServe Control Panel by clicking on Certificate Administration.

  • Two-factor authentication is not supported for 1-Touch recovery. Disable Two-Factor Authentication on the CommServe at least for the duration of the recovery.

Client

  • iSCSI disks are supported for Virtualize Me; all the backed up iSCSI disks will be re-created as regular SCSI disks on the virtual machine if they are selected during restores.

  • iSCSI disks are not supported for 1-Touch. These disks need to be manually unselected during interactive restores if any iSCSI disks are backed up.

  • SAN disks are supported for 1-Touch and Virtualize Me. For Virtualize Me, as FC HBA (Fibre Channel Host Bus Adapter) virtualization is not supported, multipath SAN disks will be re-created as regular SCSI disks.

  • Loop devices are not supported for 1-Touch, and they are not included in 1-Touch backups.

  • 1-Touch supports native Linux multipathing. Vendor specific multipath implementations are not supported.

  • 1-Touch recovery and Virtualize Me for Hyper-V is not supported if the virtual machine is generated using the Generation 2 specification.

  • For VMware ESX 6 or higher versions, set the Virtual Machine compatibility to ESXi 5.5 and later (VM version 10) during the creation of the virtual machine.

  • Itanium (IA64) processor is not supported.

  • 1-Touch recovery is supported on clients with Linux kernel executable in vmlinuz-* format.

  • 1-Touch recovery is supported for LUKS-encrypted disks with LUKS version 1.6.4 or higher. After the first phase of 1-Touch recovery, provide the passkey for encrypted disks in plain format by entering the following command on an alternate terminal:

    create /tmp/override/cryptFile.key

    where the cryptFile.key format is:

    encrypted_disk_name p passkey_in_plain_format

DISCLAIMER

Certain third-party software and service releases (together, “Releases”) may not be supported by Commvault. You are solely responsible for ensuring Commvault’s products and services are compatible with any such Releases.
