I have a house and a flat 120 km away from each other. One is the master the other the slave. The master is read/write the slave read only for the clients. They are mounted with sshfs (not ideal with interrupted WiFi connections / reconnect issues, might switch to WebDAV) by the clients Laptops, Desktop, Nokia N900es etc..
They sync with a cron job. Also they test if clients are nearby (Wifi) and rsynces them for backup purposes.
The main data is all on the master/slave servers.
I sync manually to clients if necessary for offline work(driving by train etc.)
The plug computer is a Sheeva plug.
There is a low power WD USB 1 TB drive connected, power consumption in idle is <5 W.
- pyre 15y agoThanks for replying. I imagine you also have some sort of backup regiment outside of the 'cloud.'
- holri 15y agoWhy? Do you think this is insecure?
- pyre 15y agoWell, it's a mirroring technique. Sure you're mirroring to an off-site location, but I'm assuming there is no versioning happening (i.e. snapshots). If a file becomes deleted or corrupted on the master, then that change will propagate to the slave, and you will no longer have the file.
- holri 15y agoCorrect, but one can use rdiff-backup http://rdiff-backup.nongnu.org/ http://rdiff-backup.nongnu.org/. Since I use mercurial for critical files I have some versioning.
