Thank you ;-)

Yes, exactly.
I was busy with other things this week so I haven't yet found the time
and/or the brain to work on this.
A detail to solve is:
the dump will look like
# tree /mnt/amhold/vtape/
/mnt/amhold/vtape/
└── 20191129170354
├── pre01svdeb02.ntcs-sql-latest.0
├── pre01svdeb02.ntcs-sql-latest.0.1
└── pre01svdeb02.ntcs-sql-latest.0.2
... the timestamp will change every day/run, so I need some find-command
to find the latest file (there could be more than one sometimes) and
then maybe setup a rotating symlink or so (I mean something like a
prefix "sqldump-latest" or so).
We talk about ~5GB here. Unfortunately this will be a completely new
file each day (think "binary and compressed here"), so I expect rsync to
transfer the whole file each time. This will take a few hours over that
small DSL-line ... so this will have to happen during the night.
But the rsync could be run at a completely different time.
As there are vtapes in place ... it's even possible to run a specific
"amflush -b" for that DLE after the sync.
I will try that in the next days or so.
