Please be aware that consolidation is just a method of deletion but not an alternative to deletion.
The resulting backup will not contain data that was present in the deleted backup and was
absent from the retained incremental or differential backup.
Backups resulting from consolidation always have maximum compression. This means that all
backups in an archive may acquire the maximum compression as a result of repeated cleanup
with consolidation.

Best practices
Maintain the balance between the storage device capacity, the restrictive parameters you set and
the cleanup frequency. The retention rules logic assumes that the storage device capacity is much
more than the average backup size and the maximum archive size does not come close to the
physical storage capacity, but leaves a reasonable reserve. Due to this, exceeding the archive size
that may occur between the cleanup task runs will not be critical for the business process. The rarer
the cleanup runs, the more space you need to store backups that outlive their lifetime.

The Vaults (p. 70) page provides you with information about free space available in each vault. Check
this page from time to time. If the free space (which in fact is the storage device free space)
approaches zero, you might need to toughen the restrictions for some or all archives residing in this
vault.

2.8 Backing up LVM volumes and MD devices (Linux)
This section explains how you would back up and recover volumes managed by Linux Logical Volume
Manager (LVM), called logical volumes; and multiple-disk (MD) devices, called Linux Software RAID.

2.8.1 Backing up logical volumes
Acronis Backup & Recovery 10 Agent for Linux can access, back up and recover such volumes when
running in Linux with 2.6.x kernel or a Linux-based bootable media.

Backup (GUI)
In Acronis Backup & Recovery 10 GUI, logical volumes appear under Dynamic & GPT Volumes at the
end of the list of volumes available for backup.
end of the list of volumes available for backup.
To back up all available disks, specify all logical volumes plus basic volumes not belonging to them.
This is the default choice when you open the Create backup plan page.

Basic volumes included in logical volumes are shown in the list with None in the File system column.
If you select such volumes, the program will back them up sector-by-sector. Normally it is not
required.

Recovery
When recovering logical volumes, you have two options:
Recovering volume contents only. The type or other properties of the target volume will not
change.
This option is available both in the operating system and under bootable media.
This option is useful in the following cases:

This option is available both in the operating system and under bootable media.
This option is useful in the following cases:
When some data on the volume was lost, but no hard disks were replaced.
