Is it possible to force BackupPC to perform the full backup on a certain
day of week, say on Sunday. During the workdays, full backup of our
document management system chokes up the resources.
Thats what blackout periods are for.
well, no. That's what cron jobs are for. This question is asked on a regular
basis. There should be plenty of good answers available.
They let the backups only run outside work hours unless the backup is very
important because the last backup is far to old.
That is also wrong, for two reasons:
1.) Blackouts are ignored for hosts according to consecutive good and failed
pings. The age of the preceeding successful backup is *not* factored into
the decision.
2.) Backups will not be *started* within the blackout window (if applicable).
Once they are running, they will be finished, regardless of blackout
configuration. A long running full backup may well run into your work
hours if it is started late enough in the backup window.
But you can't distinguish between full and inc backups with blackout periods.
That, at least, is true, and is the best example why blackout periods are
*not* going to be the solution
.
The only solution there is to once log in on the weekend and schedule a full
backup by hand. The following weeks, the incremental of 7 will again be on a
weekend.
Yes. Until something unexpected happens.
