Currently we have an inhouse server (Ubuntu Server 10.04), 2 computers (one Windows Vista, one Ubuntu 10.10) and a laptop (Windows Vista again sigh)... I have no expertise in the field of backups whatsoever but I manage our nifty little server. We need offsite backups. What I was thinking... Sync all computers to the server and then have the server periodically archive (password protect?) then upload to some remote location. I have no idea what the remote location will be but I assume it would be relatively cheap. The computers syncing would probably make the backup size in the region of 100-200GB? I can't be sure yet but that's probably a reasonably accurate estimate. So. Any advice, solutions or ideas?Wot Simon & Grant said .... especially the bit from Simon about getting the data back again! Realistically, you can not get it back via the Internet in a sensible time-frame for that sort of data. Also, you can not send 100-200GB over the Internet every night - well, not unless you've got a stupidly fast connection. Think in the region of 1-2GB per night on an ADSL line... So... Have you thought about tapes. Seriously. We all talk about rsync and using the Internet, but for that quantity data and ease of use, tapes are a very viable alternative. Very trusted and well understood. And reassuringly expensive, but how valuable is your data? Pick a system that will handle at least 300GB natively (forget the tapes compression ability) It will be SCSI. A very quick search finds: http://www.novatech.co.uk/novatech/prods/storage/dltstoragedrives/Quantum/TR-S34BX-YE.html
LTO 3 is a bit cheaper... http://www.novatech.co.uk/novatech/prods/storage/ltostoragedrives/29763.htmlFor that you get 400GB uncompressed and up to 800GB compressed for just under a grand. Tapes are in the region of about £25 each.
LTO 4 on the other hand offers 800GB uncompressed and up to 1.6GB compressed, but the drives look to be nearly twice as much.
They are quick though, much quicker than hard drives and much more reliable from what I've found.
Looks like the drives tend to be SAS drives but I believe SCSI models are still available too.
I'd suggest 10 to start with, then a new one each month as you create long-term archives.
I agree, if you're spending so much on a drive then you may as well buy a nice multi pack, brings the price on tapes down slightly.
