NOTE
"Autoloader" tape devices for local backup are not supported at
the time of this writing.
Backup software, such as Veritas Backup Exec 7.3 or Computer
Associates ArcServe IT 6.61, is installed on the CE and run on the
CE. Backup software backs up the CE NOS disk and the data disks
in the same manner as in a standard (standalone) system..
Semi-Local Backups
In this configuration, only two tape backup drives are used.
Two
DLT 70r drives are connected to the two IOPs and “redirected” to
the CEs in the Marathon Configuration Utility.
There are no tape
devices dedicated to the local backup of the IOPs operating system.
However, Windows NT on each IOP can still be backed up by way
of the virtual network between the CEs and the IOPs.
Peformance of
an IOP backup would be significantly slower than a dedicated tape
drive to each IOP.
Performance on the overall HPAA system will
not be impacted due to the artificial bandwidth limit imposed on the
virtual network.
