Basically, I'm searching for a rdiff-backup that can be safely interrupted (network disconnection, computer switch off, sleep), and that can develop scheduling strategies to in order to avoid interruptions (nonetheless).
Scheduling strategies would analyze computer boot and shutdown to extract patterns, to start the backups at times where the computer will be likely awake enough for the backup to complete, and maybe extract usage pattern and avoid intense usage periods (like the minutes after the boot completed).
This is complex software, and with a solution that wont be perfect, but i wonder if something like this exists, or if a combination of tools (rdiff-backup + statistical scheduling) could lead me to something similar.
