For several years now our small business has been using retrospect to backup employee's machines every evening. We have the server installed on a little windows xp based machine and it backs up whichever machines are left on to a NAS unit on the network.
The machines being backed up are a mix of Windows and Mac OS and there are rarely more than 8 machines backed up each evening.
Recently, however, Retrospect has started to become unreliable when performing these nightly backups. It routinely decides not to backup to the NAS deciding it is write protected while other nights it operates absolutely fine. The same problem happens when we connect out HDD for the off site backup.
Obviously having a backup system that doesn't work is rather pointless though thankfully the majority of data is backed up in other ways anyway.
I was wondering if anyone had some other fairly low cost backup solutions that we could look into. We would essentially be looking to perform nightly backups for 10 units (a mix of win and mac) and a regular offsite backup as well. It would need to be able to run centrally off either a Windows machine or a low cost device.
