NOTE: You may want to archive tapes storing the data from
your monthly full backups, rather than recycle those tapes.
your monthly full backups, rather than recycle those tapes.
Table 5-7 represents only a sample backup cycle based on a
five-day work backup cycle. You should implement a backup
cycle that is most effective and convenient for your environment.
The backup cycle and backup strategy you use determines the
number of tapes you need. Also, depending on the amount of
data being backed up, backups may require more than one tape.
In that case, with relation to Table 5-7, each tape is actually a
collection of tapes. For example, Tape #1 would actually be
tapes 1a and 1b, if two tapes were required to complete the
backup.

Xerox recommends that you use multiple backup media sets for
each device. Having multiple backup sets provides additional
security, in case one set is corrupted or damaged. Table 5-8 lists
the minimum recommendation for each device.
