I am struggling to find a method of keeping consistent off-site without
breaking easy restores.
My planned schedule was as follows:
First Sunday of Month: Full Backup to Disk
Monday-Saturday: Incremental Backup to Disk
Friday (after the incremental): Virtual Full Backup to Tape
Subsequent Sundays in Month: Differential Backup to Disk
Keeping 3 months (or more depending on rate of change and how well
compression works, which are currently unknowns) on disk for restores,
and the Friday virtual full going off-Site in case of disaster.
The problem I ran into (well not actually still in testing, and not
production), is on the Second Friday of the month, the virtual full
fails, because it can't find the previous virtual full to build the new
one from. How do I make it go back to the actual full instead of the
previous Virtual Full?
Will I be stuck creating a virtual full to another disk pool, then
running a copy job for off-site backups, which unfortunately greatly
reduces the history of on disk data I can keep for restores.
Or is there some method I have yet to discover that will allow me to
mark the tape volume unavailable so that it ignores that job on the
subsequent virtual fulls. I have tried playing with setting the enabled
status to disabled, and updating the volstatus parameter, without
getting anywhere.
