the original command without --listed-incremental works:

--files-from=- --ignore-failed-read --same-permissions --no-recursion \
--totals --level=0 --verbose --sparse -b 20 --file /mnt/flexbackup/mnt.0.tar
It would add each non-directory member to the archive twice. Was that
intended?
you already addressed and corrected.
# cd "/mnt" && find . -depth -xdev ! -type s -print0 | tar --create --null
--files-from=- --ignore-failed-read --same-permissions --no-recursion \
--totals --listed-incremental=/mnt/flexbackup/mnt.0.snapshot --level=0 \
--verbose --sparse -b 20 --file /mnt/flexbackup/mnt.0.tar
That's even more risky: incremental backups work by comparing
directory contents and metadata with the information stored on a
previous run. It is not a good idea to give individual files as
arguments to tar in incremental mode.
so i discovered after sending my emails, including someone in 2005
trying to do what i was trying. the documentation should state this.
To avoid archiving sockets, I'd suggest creating an exclude list
instead. E.g:
find . -depth -xdev -type s |
tar -C /mnt \
--create --null \
--files-from=- --ignore-failed-read --same-permissions --no-recursion \
--totals --listed-incremental=/mnt/flexbackup/mnt.0.snapshot --level=0 \
--verbose --sparse -b 20 --file /mnt/flexbackup/mnt.0.tar \
--exclude-from - .
i suppose that would work, minus the "--files-from=-" and "--null".
and i might be able to have --exclude work for me. thanks.
