Description Arvid Requate

2023-08-15 14:00:10 CEST

/etc/cron.d/univention-samba4-backup uses /usr/sbin/univention-samba4-backup and that doesn't work with a Samba sam.ldb that uses mdb/lmdb as backend databases. As a result customers with large sam.ldb backend databases will have no nightly snapshots in /var/univention-backup/samba which are sometimes useful in support situations.

Systems like these can be identified e.g. like this:
===
root@ucs:~# ldbsearch -H sam.ldb -b '@PARTITION' -s base backendStore                                                           
# record 1
dn: @PARTITION
backendStore: mdb

The new version of /usr/sbin/univention-samba4-backup
now generates a lot of output, that's not good for use
in a cron job.
