Finding a file as it existed months or years ago can be tedious. For

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.
