Automatic backup

[StephenUK]

I know this has been raised before several times, but I can't quite understand what is being said on the forum.

As I increasingly work in UR so the importance of not losing data from UR increases in importance.

I have now set up automatic backup on a daily basis using "VersionBackup", and sometimes backup more often than that manually. Nonetheless, some way of backing up automatically every 20 minutes, for example, would reassure me even more.

I read on the forum that there is nothing to stop backup on an open database, which sounds very helpful. But I also read that because of the large size of the databases it is not practical to implement backup. (At least, I think that is what was being said). Why is that? Why can't, for example, a one gigabyte database be backed up every ten minutes so long as the CPU usage is regulated?

Alternatively, would it not be possible for UR to backup only the actual changes to a database as they go along?
