Ask Slashdot: Simple Backups To a Neighbor?
First time accepted submitter renzema writes "I'm looking for a way to do near-site backups — backups that are not on my physical property, but with a hard drive still accessible should I need to do a restore (let's face it — this is where cloud backup services are really weak — 1 TB at 3-4mb downloads just doesn't cut it). I've tried crashplan, but that requires that someone has a computer on all the time and they don't ship hard drives to Sweden. What I want is to be able to back up my Windows and Mac to both a local disk and to a disk that I own that is not on site. I don't want a computer running 24x7 to support this — just a router or NAS. I would even be happy with a local disk that is somehow mirrored to a remote location. I haven't found anything out there that makes this simple. Any ideas?" What, besides "walk over a disk once in a while," would you advise?
Bitorrent sync is a very simple way to go if you don't want to be too worried about backup administration. Just set up a read-only share for directories on the remote machine and put password protected encryption on the remote share.
That will give you at least some measure of protection from the remote server owner reading your files and they won't be able to nuke your local copies. Btsync is the most no-fuss, transparent backup solution I've used so far. I've got 4 personal machines that it's syncing right now and aside from a couple minor issues in earlier releases, it's been reliable, fast and has a minimal amount of administration you have to deal with.
Too painful and expensive. This can be made much simpler. I have two sets of backups I keep: an internal 2 TB hard drive for local backups, and a pair of 1 TB external drives for off site backups. Every Monday, I unplug the external drive at my house as I head out the door for work. At work, I put it into my locker and retrieve the other drive, which I bring home with me when I leave for the day. When I get home, I plug it into the vacant USB and power cord, and presto: it's online and ready for backup! My software (I use ShadowProtect Desktop) does a full backup of the machine every Sunday night, so Monday mornings it is always ready for the swap again. It's a very quick and painless way to have offsite backups without spending a fortune on comparatively slow Internet bandwidth.
Beware of bugs in the above code; I have only proved it correct, not tried it.
