First, thanks to everyone who replied to my question the other day. I saw some great suggestions to give me leads on things to try.
Second, I was thinking on this over the weekend and had come up with something similar to the suggestion below, however, I noticed you can get 800GB external USB drives now. Has anyone considered taking the external USB drive and rsyncing to that and sending that off site? an 800GB drive is only about $600 and as someone else pointed out, a proper new tape setup will run upwards of $8k now. Could buy quite a few USB drives for that. Has anyone tried doing anything like that? I think I'd rather do rsync than xfs_copy because then when the drive comes back in rotation, I only have to copy over what has changed, rather than dumping the whole file system. For right now, I could fit everything on an 800GB drive - not sure if new ones will grow in size fast enough to keep up with me as my data grows, but I would imagine worst case, you could take two of them and join them with LVM somehow, couldn't you? What would be the pitfalls with this? Do these drives usually travel well? (meaning, tapes aren't so big a deal if the courier bounces them around - could an external usb drive stand up to that or would it need to be packed special?) Any other thoughts? Thanks! -Ken On Mon, 2006-03-06 at 13:11 +0100, Olivier LAHAYE wrote: > Le Thursday 02 March 2006 19:19, Ken Long a écrit : > > I've been trying to search through this list and through google to > > figure out the answer to this question, but have not found a good answer > > yet. > > > > We are using USB2 Disks for offsite storage with xfscopy. > Our BackupPC data is stored on a 1.6TB RAID5 disk bay on an XFS filesystem. > The actual physical used space is about 300GB. > To backup the thing, we are doing an xfscopy into a file on the mounted USB2 > drive (which is 400GB).
