Thank you.

Seems I don't know, what I'm doing here, right? I want to avoid corrupt 
dbs. From

https://www.samba.org/samba/docs/man/Samba-HOWTO-Collection/tdb.html:

Those who package Samba for commercial distribution with operating 
systems and appliances would do well to take note that tdb files can get 
corrupted, and for this reason ought to be backed up regularly. An 
appropriate time is at system shutdown (backup) and startup (restore 
from backup).
[...]
It is recommended to backup all tdb files as part of the Samba start-up 
scripts on a Samba server.

This is, what I'm doing.

But the HowTo is too old, no gencache_notrans.tdb and other new tdbs in 
it. And I cannot find an information, which databases are created with 
CLEAR_IF_FIRST. That's why I backup all tdbs in

/etc
/run/lock/samba

after wiping not persistent ones.

If I should not clean gencache.tdb on start, this seams to be an tdb, 
which is not created with CLEAR_IF_FIRST.

I've had trouble with this in the past. At some version change printer 
driver informations are gone from the printing directory to registry.tdb 
and I wiped registry.tdb ;-)
