To be honest, Debian has a suggestion to do it. Not in start/stop scripts but more in regular maintenance tasks: http://bugs.debian.org/473651 ...which we tagged "wontfix" on the rationale that setting such backup tasks should be up to the local administrator..just like any other backup policy. > I was thinking of running it every day as a chron job (not restarting > Samba) and saving some backlog (some days worth of old backups).

In the bug report mentioned above, it was observed that several TDB files do actually deserve to be preserved. Noticeably, these are those we put in /var/lib/samba on Debian systems: bubu...@mykerinos:~> ls -l /var/lib/samba/ total 228 -rw------- 1 root root 8192 mai 17 2007 account_policy.tdb -rw------- 1 root root 86016 oct 6 2007 group_mapping.ldb -rw------- 1 root root 8192 mai 17 2007 group_mapping.tdb.upgraded -rw------- 1 root root 8192 mai 17 2007 ntdrivers.tdb -rw------- 1 root root 696 mai 17 2007 ntforms.tdb -rw------- 1 root root 8192 mai 17 2007 ntprinters.tdb -rw------- 1 root root 16384 mai 17 2007 passdb.tdb drwxr-xr-x 2 root root 6 avr 24 2007 perfmon drwxr-xr-x 10 root root 106 mai 9 2008 printers -rw------- 1 root root 65536 mar 31 19:20 registry.tdb -rw------- 1 root root 8192 mai 17 2007 share_info.tdb drwxrwx--T 2 root sambashare 6 nov 17 2007 usershares -rw-r--r-- 1 root root 4096 mai 31 2007 winbindd_idmap.tdb -rw-r--r-- 1 root root 247 déc 8 06:34 wins.dat This is on my laptop system where many Samba features such as printing are not used.....and which may have some cruft left by old broken packages.
