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. 120) 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.

Backing up dynamic volumes (Windows)
This section explains in brief how to back up and recover dynamic volumes (p. 394) using Acronis
Backup & Recovery 10. Basic disks that use the GUID Partition Table (GPT) are also discussed.
Dynamic volume is a volume located on dynamic disks (p. 393), or more exactly, on a disk group (p.
392). Acronis Backup & Recovery 10 supports the following dynamic volume types/RAID levels:
simple/spanned
striped (RAID 0)
mirrored (RAID 1)
a mirror of stripes (RAID 0+1)
RAID 5.
Acronis Backup & Recovery 10 can back up and recover dynamic volumes and, with minor limitations,
basic GPT volumes.
Backing up dynamic volumes
Dynamic and basic GPT volumes are backed up in the same way as basic MBR volumes. When
creating a backup plan through the GUI, all types of volumes are available for selection as
Items to
back up
. When using the command line, specify the dynamic and GPT volumes with the DYN prefix.
Command line examples
trueimagecmd /create /partition:DYN1,DYN2 /asz
This will back up DYN1 and DYN2 volumes to the Acronis Secure Zone.
trueimagecmd /create /harddisk:DYN /asz
This will back up all dynamic volumes in the system to the Acronis Secure Zone.
The boot code on basic GPT volumes is not backed up or recovered.
