HP Serveur lame HP ProLiant BL465c Gen8 - Manual (Page 436)

• Continuous Access Synchronous is configured between disks P1 and P3 , and between disks P2
and P4 .
• Using the RAID Manager configuration definition file, the pair definitions on the database server
and backup server have been completed for the primary and secondary volumes.
• Using the RAID Manager configuration definition file, the pair definitions for remote copying
between the primary volume at the local site and the primary volume at the remote site (secondary
volume/primary volume) have been completed.
• The secondary volumes are mounted only when needed, at the following mount locations:
• Disks
S1 and S3 are mounted as W: drives.
• Disks S2 and S4 are mounted as X: drives.
Backing up concurrently at both local and remote sites
The following subsections give an example of backing up both the local site and the remote site
concurrently.
Operation at the local site
Execute VSS backup to back up data concurrently to the secondary volumes at both the local and
remote sites.
Execute the
drmexgbackup
command on database server A:
An unused backup ID is assigned to each server. For this example, we assume 0000000001 as the
backup ID at the local site, and 0000000011 as the backup ID at the remote site.
DBServer A > drmexgbackup -mode vss -cascade -auto import -auto mount G:
