Points to note during system configuration
When repeatedly using a single data cartridge, all the data can be lost if the backup fails. Also, if a
backup data cartridge becomes damaged, the data cannot be recovered. Damage in the event of a fail-
ure can be minimized if two or more data cartridges are used for backup operation.
Example: Using different data cartridges for each day of the week.
