Thanks for the prompt reply.
Machine A is an old Buffalo TeraStation. Ironically, it is running Linux &
likely even has rsync, but as a practical matter, SMB is the only available
1) You can touch the files, or copy them in such a way that their times
No shell access to A for "touch". No option I can find via the web
interface to have the copies to A take the current time as their
creation/mod time, though this would be great, if possible.
2) You can simply run full backups
Performance hit? I understand pooling will avoid creating multiple copies,
but cost in backup time?
3) You can switch from SMB to rsync
Love to. I understand there are "hacked" firmware versions for the
TeraStation which would allow this, but I'm very reluctant.
I guess I'm mostly surprised that the incremental backup does not realize
that there are files in the source that do not exist in the destination &
back them up based on that, regardless of modtime.
