Dynamic volume

Any volume located on dynamic disks (p. 233), or more precisely, on a disk group (p. 233). Dynamic

volumes can span multiple disks. Dynamic volumes are usually configured depending on the desired

goal:

 to increase the volume size (a spanned volume)

 to reduce the access time (a striped volume)

 to achieve fault tolerance by introducing redundancy (mirrored and RAID-5 volumes.)

Encrypted archive

A backup archive (p. 228) encrypted according to the Advanced Encryption Standard (AES). When the

encryption option and a password for the archive are set in the backup options (p. 228), each backup

belonging to the archive is encrypted by the agent (p. 228) before saving the backup to its

destination.

Encrypted vault

A managed vault (p. 237) to which anything written is encrypted and anything read is decrypted

transparently by the storage node (p. 239), using a vault-specific encryption key stored on the node.

In case the storage medium is stolen or accessed by an unauthorized person, the malefactor will not

be able to decrypt the vault contents without access to the storage node. Encrypted archives (p. 235)

will be encrypted over the encryption performed by the agent (p. 228).

Export

An operation that creates a copy of an archive (p. 228) or a self-sufficient part copy of an archive in

the location you specify. The export operation can be applied to a single archive, a single backup (p.

228) or to your choice of backups belonging to the same archive. An entire vault (p. 240) can be

exported by using the command line interface.

Full backup

A self-sufficient backup (p. 228) containing all data chosen for backup. You do not need access to any

other backup to recover the data from a full backup.

GFS (Grandfather-Father-Son)

A popular backup scheme (p. 229) aimed to maintain the optimal balance between a backup archive

(p. 228) size and the number of recovery points (p. 238) available from the archive. GFS enables

recovering with daily resolution for the last several days, weekly resolution for the last several weeks

and monthly resolution for any time in the past.
