3. Label the first unit of backup media.
Single or Sequential Label the first unit Volume 1 of
n . Replace n with the
total number of units of backup media--if you use more
or fewer tapes than you planned, you may have to
change this number when you finish storing the files.
Label the second unit of backup media Volume 2 of
n .
Label the third unit of backup media Volume 3 of
n , and
so on.
Parallel or Parallel Pools Label each piece of media with both the reel number
and the set number. Label the first media of each
parallel device or device pool as
Volume 1 of "x", Set 1 of "y"
where "x" is the total number of media allocated to the
particular parallel set, and "y" is the total number of
parallel sets. If you use more or fewer units of backup
media than you planned, you may have to change the
final number of volumes when you finish.
For example, if you plan to use four units of backup
media with two parallel devices, label:
a. First media as Volume 1 of 2, Set 1 of 2.
b. Second media from the first parallel device as
Volume 2 of 2, Set 1 of 2.
c. First media from the second parallel device as
Volume 1 of 2, Set 2 of 2.
d. Second media from the second parallel set as Volume
2 of 2, Set 2 of 2.
4. In addition to the media number, write the following information on each media's label:
• The current date which serves as a reminder of when the backup was created.
• The name of your computer system.
• A list of the files you intend to store, or if the tape is from a system backup, write
either "FULL BACKUP" or "PARTIAL BACKUP".
• If you plan to use interleave format, write "INTERLEAVE". (Interleave format is
described in Chapter 5, "Storing Files.")
• Any other important information about the backup. Since it is a STORE backup, write
"STORE".
• Your name or initials.
• The date after which the information on the backup is obsolete, called the Purge
Date. If you keep STORE backups indefinitely, make a note to that effect.
• The number of times the backup media has been used, under the heading "Cycle".
