+/*
+
+ 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.
