[Samba] notice backup script update!

[L.P.H. van Belle]

Hai, 
 
For the people using my modified backup script.  
Found here: 
https://github.com/thctlo/samba4/tree/master/backup-script 
 
I've updated it, due to bug https://bugzilla.samba.org/show_bug.cgi?id=13088   netlogon_creds_cli.tdb will be excluded from the backup. 
Due to this the script exits and does not backup anything since netlogon_creds_cli.tdb is the first it wanted to backup. ( in my case ).
 
Keep_days is working now also. 
Tip here is, set you DAYS high, i've set a default of 60 days now and if KEEP_DAYS="yes" then all files older then 60 days will be removed from the backup, except dates with -01- -15-  . 
 
Update you backup script or please do check if its running as it should. 
I have not checked the original by samba source provided backup script, just beware and check it. 
 
 
Greetz,
