Finding a file as it existed months or years ago can be tedious. For example, find A/MailMessages as it was at 2023.02.07. Otherwise the backup system works well.
On one computer I use rsync to do what appear to be complete backups, only files identical to the previous run are hard-linked. This appears to fail sometimes (not sure under what conditions), so I wrote scripts to find identical files and link them. I think the scripts are too complex for my pea brain to debug them successfully, so there are errors. But they seem to work.
I can imagine a complete copy of A onto an external drive for each backup; but with most files in A not changing during the backup interval, that is inefficient.
When rsync works, that is exactly what it fixes. When I boot the file server (possibly today but definitely tomorrow) I'll post my backup script. -- Most people don't even know what sysadmins do, but trust me, if they all took a lunch break at the same time they wouldn't make it to the deli before you ran out of bullets protecting your canned goods from roving bands of mutants. -- Peter Welch
