Tape label(s) field
The term tape label refers to the software label name of up to six
characters you supply for a tape. The term does not apply to a label
you physically attach to the tape. Tape labels allow BACKUP Manager
to identify a tape and determine its characteristics.
Label your tapes according to the data contained on the tapes. The
following table shows some suggestions for labeling tapes:
Label Type of Backup
------ ----------------------------------
DLY101 Daily, Group 1, Volume Number 01
DLY102 Daily, Group 1, Volume Number 02
WKY101 Weekly, Group 1, Volume Number 01
WKY201 Weekly, Group 2, Volume Number 01
MTH101 Monthly, Group 1, Volume Number 01
YRY101 Yearly, Group 1, Volume Number 01
After mounting a tape, BACKUP Manager processes information stored in
the tape-volume header record before writing to the tape.
Specifically, BACKUP Manager does the following:
· Checks the tape-volume protection information to ensure that you
have the right to access the volume in the manner you requested.
· Checks the tape expiration date to prevent you from initializing a
tape that has not yet expired.
· Compares the tape volume label you specify to the tape volume
label of the tape to ensure that you do not create a save set on
the wrong tape. BACKUP Manager uses the following guidelines when
processing tape labels:
- If you specify a label that is longer than six characters,
BACKUP Manager truncates (shortens) the label to the first six
characters.
- If the volume label is fewer than six characters long, BACKUP
Manager adds spaces to lengthen the label to six characters.
- The first four characters of the tape volume label either
(a) must match the first four characters of the label you
specified, or (b) must end with one or more underscore characters.
For example, the volume label ABN_ matches the ABN label
specification but does not match the ABNE label.
- If the fifth and sixth characters of the tape volume label are
numbers between 0 and 9, BACKUP Manager does not compare these
characters with corresponding characters in the label you
specified. Otherwise, the fifth and sixth characters in the
tape volume label must match the corresponding characters in
the label specified in the BACKUP Manager command line.
