LVM snapshotting

This option is effective only for Linux operating systems. This option is effective for both disk-level and file-level backup of volumes managed by Linux Logical Volume Manager (LVM). Such volumes are also called logical volumes.

This option defines how a snapshot of a logical volume is taken. Acronis Backup can do this on its own or rely on Linux Logical Volume Manager (LVM). Use of a snapshot ensures a time-consistent backup of a volume whose data may change during the backup process.

The preset is: Acronis Backup

Select one of the following:

Acronis Backup will take the snapshot on its own. With this setting, a backup normally proceeds faster and unallocated space on the volume group is not required. Therefore, we recommend changing the preset only if you are experiencing problems with backing up logical volumes.

Acronis Backup will use the snapshot taken by LVM. This snapshot is stored on unallocated space of the volume group. If the unallocated space is missing, Acronis Backup will take the snapshot on its own.
