1-Touch for Linux: System Requirements

Verify that your environment meets the system requirements for 1-Touch on Linux.

Operating System: Client

Important

Use the most recent version of the operating system that is listed. The Commvault software fully supports the most recent version of an operating system, until the vendor ends support. More recent versions of the Commvault software might not install on operating systems that are not supported by the vendor anymore. For information about the support lifecycle of an operating system, contact the vendor.

Hard Drive

5 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.

Processors

Peripherals

A CD-ROM drive or the 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 that are required for 1-Touch, see FAQs - Operating system utilities to perform 1-Touch recovery.

Driver Modules

The usb-storage module must not be blocked from the system.

Bootloader

File System and Volume Managers

  • 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

Because snapshot volumes are not recovered as part of the 1-touch recovery, mount and back up the snapshot data.

Virtual Machines

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 more recent 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.

  • FCoE (Fibre Channel over Ethernet) 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 more recent versions. 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

    Note

    Entries for LUKS-encrypted partitions and LV's will be excluded from the final fstab.

    Example

    For an encrypted disk /dev/sdb1 opened as luks1 during backup, the key file must be in the following format:

    /dev/mapper/luks1 p passkey

    Note

    To open multiple devices, add an entry for each device on a new line.

  • Booting a HPE ProLiant DL380 Gen10 hardware with a 1-Touch ISO file attached via iLO fails. Use a different method to attach the ISO.

  • Booting the destination machine from a 1-Touch ISO file on a bootable USB is not supported.

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.
