Hi,
I'd like to automate the backup of my multiple raspberry pi (osmc, teleinfo, home-automation, ...).
Some of them are not easily accessible, so unplug the sd card and make an iso image is not a convenent way to go.
I've googled for such a solution, and found post about "dd over ssh" or "rsync".
But I think it's over my competences, so need a little help
The best would be to make incremental image backups every nights.
The rpi image/filesystems will not change a lot (except logs, some local DBs...) because all data are stored in the nas and accessed in NFS/SMB.
If incremental backup is not possible, a rolling backup maybe (keep the last 10 backups for example)
Concerning the backup format, the simplier in case of rpi sd crash would be to have *.iso images. (but not compatible with the "incremental" way i suppose).
Don't know if it's even possible to make an image of a running linux system...
Any help or suggestion would be geatly appreciated
And if I have time and skills, I could try to make a plugin.
thanks
