Backup performance/capacity
The backup performance and backup capacity that can be used in one data
cartridge varies depending upon the following factors:
●
The conditions (attrition, dust, etc.) of the recording surface of the data
cartridge to be used
●
The dust and dirt condition of the product's magnetic head
●
The data compression rate
●
The workload on the server

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 failure can be minimized if two or more data cartridges
are used for backup operation. For example, use different data cartridges for
each day of the week.
