My desktop Linux machine (which is always running) doubles as the backup server, backing up itself, a couple of RaspberryPi’s (one Kodi, one home automation) and my SO’s windows machine. Backup using rsnapshot to an external USB drive that is LUKS/dm-crypt encrypted. Every Wednesday the SO swaps the USB drive with a sibling kept at her office. I really like the way rsnapshot works with complete looking images for each backup, but unchanged files are hard-linked across images. Makes it super easy to just mount the drive and grab the backup of that file I just corrupted. For the windows machine, I’m using Cygwin to run an SSH server and rsync. Before running rsnapshot, the backup script sends a wake-on-lan to the PC, then SSH in to run a batch file that sets the go-to-sleep timeout to never, and make a shadow copy of the drive which is what goes to the backup. Then rsnapshot does its rsync over ssh thing to do all the backups. Afterwards, SSH again to run a batch file that cleans up the shadow copy and resets the go-to-sleep timeout back to twenty minutes. § Unfortunately I’ve got some sort of weird problem where it dies while doing the backup of the root folder on the local drive. I’ve run spinrite on the drive, and blown the dust out of the machine, but no change. Last time I had this problem the power supply was failing under demand, but I’ve stress tested it and that doesn’t seem to be the cause this time… sigh. Bit hard to gather diagnostics as the machine is completely locked up when I come in the next morning…
