5.8.2
Data compression rate
This product has a data compression function included in the hardware.
Although the data compression rate is approximately 250%, it varies depending
on the data content.
Data that has already been compressed by software is not effected by this
product.
Some backup software has a data compression function prior to transfer,
however, do not compress data by software if the hardware compression
function is on.
5.8.3
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
5.8.4
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.
