Haxxup – cheap remote backup

The pains and guilty consciences from having a lacking backup concept established are widely common. I honestly don’t know anyone (and I mean it) that can say that they have their (home, private) backup covered with a straight face. We all know we should backup locally and remotely, so that we can do fast recovery for the easy things we mistakenly remove or ruin, and if we get burgled or the house burns down we need to have a backup remotely.

The importance of private computer backups has only increased over time, as these days most of us have vast amounts of family pictures and videos stored as well, things that in the old days were stored (and lost) separately.boom

A growing problem with remote backups is of course that we all have ridiculous amounts of data to backup. Getting a commercial remote backup deal for say 300GB (and growing) isn’t cheap. And we’re also very often at loss when it comes to get a solution that works on Linux.

In Haxx, we also recognized and suffered from these problems. We came up with a scheme to fix a distributed networked backup among ourselves! Getting large hard-drives to use locally is fairly cheap. We all have fairly good fixed-fee no-bandwidth-limit internet connections (although admittedly the uplink speeds are lacking for us typical ADSL users).

We decided that among us 4, each of us gets an account at two of our friends’ servers and we’ll be able to upload our backups to those at our own pace to store whatever we want. We decided on getting two places for everyone to decrease the risk even further, especially if you for example urgently need to get something back and one of us have a network problem (not completely unheard of) or something else.

My current total backup is about 100GB and I have a 1mbit uplink. If I use the entire bandwidth for this, other things get a little sluggish so I’ve capped the rsync job to 90KB/sec… My first run thus completed in roughly 13 days. Luckily I don’t add contents at a very high pace so the ordinary sync jobs from then on should be much smaller and should be able to complete within hours. As long as I add less than ~3.5GB during a 24 hour period, it should be able to keep up to sync to two remote places.
