I have a backup script that runs on post-commit. If anyone wants to use it here you go.
Details:
wsf script (windows scripting file)
does full backups every 10^n (can't think of a better way to describe this)
- full @ 10, 100, 1000, 10000
does incremental backups every commit
- ten incrementals at most
eg 275 rev => pack.000-099.bak.gz (full)
pack.100-199.bak.gz (incremental)
pack.200-275.bak.gz (incremental)
Problem:
Ok, so it doesn't actually work yet. I was hoping someone would look at it and decide they want to use it and be able to tell me what I am doing wrong.
I've had the script in place for a while and can't get it to work. As the usage of the svn increases here, I am getting concerned about a DB corruption (due to improper backup techniques).
I am working on a recovery script as well.
