I'm now also looking for a handy program, a lot of testing needs to be done
to find one. I guess that anything is good as long as it's
* regular (automated, because a human being tends to forget)
* frequent (sometimes you get a lot of work done quickly)
* on another disk or encrypted off-site (disks fail, fires etc)
* delta-based (not copying what's not changed, e.g. rsync)
Having made manual backups now, it's time for the quest for the backup
program!
This is kinda funny, this is the first disk that died on me. And I've been
poking at the keyboard for 25 years now. I guess it was about time for me to
wake up and smell the bit bucket. Sure, many disks get very loud as the years
pile on but that'd been all, until now. Live and learn.
