Chapter 3, Online Database Backup

Making a Backup of an Online Database on the Same Host

Note On Linux, use the -t option, and on AIX, use the -V option, instead of the -F option

for both commands.

Back up the file system at this point using a command such as bpbackup in VERITAS

NetBackup. After the backup is complete, use the following command to unmount the file

system.

# unmount mount_point

Repeat steps 2 through 5 each time that you need to back up the volume.

In some instances, such as recovering the contents of a corrupted volume, it may be useful to

resynchronize a volume from its snapshot volume (which is used as a hot standby):

# vxsnap -g diskgroup restore volume source=snapvol destroy=yes|no

The destroy attribute specifies whether the plexes of the snapshot volume are to be reattached to

the original volume. For example, to resynchronize the volume dbase_vol from its snapshot

volume snap2_dbase_vol without removing the snapshot volume:

# vxsnap -g dbasedg restore dbase_vol source=snap2_dbase_vol \

destroy=no

Note You must shut down the database and unmount the file system that is configured on the

original volume before attempting to resynchronize its contents from a snapshot.
