Summary: [FMR]: Add an option to only delete files once they
expire
Product: rsync
Version: 3.0.4
Platform: x86
OS/Version: Linux
Status: NEW
Severity: enhancement
Priority: P3
Component: core
AssignedTo: way...@samba.org

A really nice feature (since rsync is used quite a lot for backups) would be to
have a command line option to only delete/prune files when they expire rather
than as soon as they are non-existent on the source host.
For example, using --delete-during will delete any files on the destination
host that are no longer on the source host. However, it might have been a
mistake to remove the file on the source host or perhaps its not present due to
hardware failure (many scenarios spring to mind). If a nightly rsync backup is
in operation then the files will be lost forever on both the source and
destination hosts on the day of deletion.
With an option like:
--delete-expiry 30
...could ensure files are only deleted/pruned if they no longer exist on the
source host AND that their modification time on the destination host is older
than (in this example) 30 days. Exactly like this:
find /src -type f -mtime +30 -exec rm -f {} \;
One flaw is that you could potentially delete a file on the source host that
has already expired on the destination host, but for the majority of files
accessed frequently you can be rest assured you will still have a few days to
retrieve the file before its gone forever.
