I only recently noticed the -N option to smbtar

on a file's timestamp being newer than a control

Using the archive bit, as is now done, has several
problems. For example, other apps might change the
archive bit and using it as the control only allows
a single level of incremental.

Has the use of the -N option for samba-based backups
been considered?  And maybe found wanting?

We have considered using -N option in testing. One drawback is that we need

to touch  a file (one file for each backup level) in the share when we
do backup.

This would mean the samba user should have write permission on all the shares

being backed up.

Any feedback on this option is welcome. Should we include it in Amanda source?

I have cc'ed amanda-users to get more feedback.

I'm not a MS-win expert, but Amanda currently uses the archive-bit of
each pc-file to be able to do at least a lvl 1 incr backup.

When Amanda schedules a full backup it needs to reset this archive bit. Don't you need write access to the share for this.
