Optimizations options (KVM)

The following options set the type and scope of the KVM virtual machine backup.

Table: Optimizations

Option

Description

Enable file recovery from VM backup

This option allows restore of individual files from the backup. With or without this option, you can restore the entire virtual machine.

To perform a KVM backup to a deduplication storage unit, select this option. This option provides the best deduplication rates.

To back up a virtual machine that contains Arctera InfoScale volumes, disable this option. Also make sure that the Exclude deleted blocks option is disabled.

Note:

For a Linux virtual machine, the name of an LVM volume can include any of the following special characters: . (period), _ (underscore), - (hyphen). No other special characters are supported. If other special characters are in the volume name, the Enable file recovery from VM backup option does not work. As a result, you cannot restore individual files from that volume.

Exclude deleted blocks

Reduces the size of the backup image by excluding any unused or deleted blocks within the file system on the virtual machine. This option supports the following file systems: Windows NTFS, and Linux ext2, ext3, ext4, and XFS.

This option uses proprietary mapping technology to identify vacant sectors (allocated but empty) within the file system.

To back up a virtual machine that contains Arctera InfoScale volumes, disable this option. Also make sure that the Enable file recovery from VM backup option is disabled.

Exclude swap and paging files

Reduces the size of the backup image by excluding the data in the guest OS system paging file (Windows) or the swap file (Linux).

Note:

This option does not exclude the swapping and paging files from the backup: it only excludes the data in those files. If the files are restored, they are restored as empty files.

Note:

For a Linux virtual machine, this option disables the swap file when you restore the virtual machine. You must reconfigure the swap file after the virtual machine is restored. To allow the virtual machine to be restored with its swap file enabled, do not select Exclude swap and paging files.
