old backups from 4.0.5_GA taking up too much space!

[riccadus]

I'm currently running 4.5.2 network edition.

When I upgraded from 4.0.5 to 4.5.0 over a month ago I noticed the upgrade script created a /opt/zimbra/backup/4.5.0_GA/4.0.5_GA-5.2 folder.

This appears to be a backup of the backups (I assume in case something went horribly wrong?) and is quite large. This has basically doubled the size of the backup directory.

Does anybody know if I still need this folder or can I remove it? I'm not sure if it will affect restoration of my current backups at all. I would rather it not be there if its no longer necessary.

Thanks

Assuming that your system is working OK (backup is running OK and you're happy with it) and you don't need to revert then you can delete that extra directory.
