The Log Detective backups eat 100G

[praiskup]

The proposal from @jpodivin was to avoid the redunancy (if no new updates happen in the database, do not store additional tarballs, or do /bin/hardlink with reproducible tarballs).

We can also find -mtime +100 -delete or alike.

I have a set of flags we can use to get reproducible tars. We can apply them, followed by hardlink invocation to cut down the storage use.

  --sort=name --format=posix
  --pax-option=exthdr.name=%d/PaxHeaders/%f
  --pax-option=delete=atime,delete=ctime
  --numeric-owner --owner=0 --group=0
  --mode=go+u,go-w --mtime=@0
