accessing the media. It is possible to view the content of a backup archive located on a tape through
the console, even if a tape library is turned off, due to content information stored in the database. To
create an incremental or differential backup of data, the program uses the database instead of
loading, mounting, rewinding and reading a tape with the full data backup. However, a tape should
be read, for example, to validate (p. 351) a backup or to recover data from a backup.

A tape library can be locally attached to a machine the agent is installed on, but only in the case the
library is considered as a single tape drive. The agent can use such device to write and read data
backups, but the backup’s format differs from the format of the backups on the tapes written
through the storage node. To get information about the readability of the archives on tapes, written

Acronis Backup & Recovery 10 enables you to set up distribution of backups by media. For example, a
separate tape set can be used to back up some specific data, and the backups of all other data will be
written onto any currently mounted tape, which does not belong to the tape set. See the Tape
options (p. 109) section for more information.

The backup schemes (Grandfather-Father-Son (p. 32), Tower of Hanoi (p. 36)) considerably assist you
with creating effective schedule and retention rules for backups on a tape library. In combination
with the tape options, the backup schemes enable you to reuse, in automatic mode, the tapes that
are considered as free after backup deletion. See the Tape rotation (p. 139) section for more
information.

Hardware
A tape library (robotic library) is a high-capacity storage device that contains the following:
•
one or more tape drives
•
multiple (up to several thousand) slots to hold tape cartridges
•
one or more loaders (robotic mechanisms) intended for relocating the tape cartridges between
the slots and the tape drives
the slots and the tape drives
•
barcode readers (optional).
Each tape may have a special label attached to the side of a cartridge and comprise of:
•
a barcode to scan by a special reader that is usually mounted on a loader
•
a readable barcode digital value.
Such labels are used for tape identification in a tape library or especially in off-site storage.
If all cartridges in a tape library have barcodes, the library is ready to be automatically managed by
software.
software.
Tape libraries are a cost-effective solution for data storages with huge capacity. Moreover, tape is
perfect for archiving because cartridges can be stored off-site for enhanced data security. However
reading even a small amount of data from a tape library takes much more time (from several seconds
to several minutes) than from other types of data storages. The best practice of tape usage is "LESS
requests to write/read LARGER amount of data". So systematic access to very large quantities of data
is more suitable for a tape library than random access to small portions of data.
