[Notes for double backup]
(1) Backup job
There are the following notes for double backup
configuration.
Configure 2 sets of SAS controller/SAS cable/Backup
device. Two backup devices are recognized separately by
OS.
When automatically backup by a job, make a job for each
backup device so that each device can backup. In case one
device fails, the other backup device can backup.
(2) Note for BrightStor ARCserve backup
When making a job, backup is not performed if you put [*]
in the [group] of destination tab.
Be sure to configure two backup jobs with setting the
device group at the group on the destination tab and the
media definition as
“*” or the name of the media.
