I read quite a lot of posts, wiki pages and web pages about backup tools including Bacula and backupPc. For BackupPC I read the official documentation. I am looking for a automatic backup solution as replacement for Clonezilla backups.
It strikes me as weird that I did not come across any references to system consistency in the tutorials. Wouldn't that be one of the first things coming up when when thinking about automated server backup? What about MySQL databases, what about large content (email, blog, shops, git) that might change while being backed up. I would except the tools provide features to automate DB dumps, to start and stop services when their files are about to be backed up. As services distribute their files all over the place I would expect that to be a non-trivial and very time consuming planning. Further some services like NTP, LDAP, Samba might be involved in user and services authentication and can be shut down only when a backup server takes over (which should not be backed up at the same time...). Then to include user warnings that something is going to be offline in 5-4-3-2-1-0 minutes, etc. I think you get the point.
So now I have the feeling that I am overlooking some really trivial solution here. I would be very glad if someone could release me of that mental lock and point me to some place where I could follow a start-to-end tutorial covering to backup of a server including services.
The comments show me that my question could be misunderstood. Please let me rephrase the question to:
"With what I said above, how did you solve those issues for your environment?"
I am happy for any information about stuff that actually worked in the field.
thanks for reading.
