RE: Backupedge

Posted By:
Date:


Another variation on the external back up and restore which requires Informix
mirrors but makes the engine unavailable only briefly:

1-Run onmode -c block to checkpoint and block new work
2-Run onspaces to drop each chunk's mirror
3-Run onmode -c unblock to release the engine for work
4-Option (if your disks are not mirrored external to Informix) Run onspaces to
add a second set of mirror drives to each chunk for safety
5-Backup the mirror set that was removed (if you use option 4 these will be the
replacement mirrors for the next backup and that step 4 set will be backed up
next).

If you use external mirroring at the OS level you can do something similar and
some systems even permit 2 mirror sets to be live concurrently so you are not at
risk while the third set rebuilds. In that case you would run with one primary
and two mirrors normally and one mirror while the breakout set is being
archived. Then you would add a step 6 to readd the second mirrors back in.
