-
-  This program is meant for backup/restore of tdb databases. Typical usage would be:
-     tdbbackup *.tdb
-  when Samba shuts down cleanly, which will make a backup of all the local databases
-  to *.bak files. Then on Samba startup you would use:
-     tdbbackup -v *.tdb
-  and this will check the databases for corruption and if corruption is detected then
-  the backup will be restored.
-
-  You may also like to do a backup on a regular basis while Samba is
-  running, perhaps using cron.
-
-  The reason this program is needed is to cope with power failures
-  while Samba is running. A power failure could lead to database
-  corruption and Samba will then not start correctly.
-
-  Note that many of the databases in Samba are transient and thus
-  don't need to be backed up, so you can optimise the above a little
-  by only running the backup on the critical databases.
