With consistent I mean it like in the mentioned blog article from Lars. We want to take a backup of our data in one specific time range, where the data is consistent in that time range.
My thoughts till now:
I want to do a full backup of our data every Saturday. During the week I want
to take an incremental backup every 24 hours. It seems possible to do that with
the export tool. For example, I want to take a (incremental) backup every
midnight, I start the export tool five minutes after midnight with timestamps,
where the starttime is 0 (or timestamp of the last backup if it is an
incremental backup = midnight of the day before). Endtime is now - 5 Minutes =
midnight. This data we can backup on a different machine/backup server.
It seems, that the article of Lars meets exactly my requirement, that's why I'm
asked, if it is still up-to-date.
Taking snapshots with the snapshot tool gives me no data to pack on backup
server, I guess.
bye,
Timo
