 the script writes multiple log files. First of all it writes a new log file for every invocation to /tmp/<date-time>.log. this is a general log which contains information printed by the "queue manager". It then writes two log files for each backup job it runs. these can be found in the same directory where these backup jobs are stored (defined by ''BASEDST'') again with the start date and time of the job. one ends on ''log'' the other one ends on ''.err''. the ''.log'' file contains the standard-output of the process and the ''err'' file contains the standard-error output. so if copying a file failed for example it should be listed in the ''err'' file.  the script writes multiple log files.

 +===== Known Issues =====
 +On systems with old rsync versions (i.e. 3.0.6) and if your data contains extended Attributes or ACL's you may get lots of ''Missing abbreviated xattr value, trusted.SGI_ACL_DEFAULT'' messages in your logs. Also your backup may get bloatet because files with ACL's or extended Attributes are constantly re-downloaded. This is due to some issues with ACL and Xattr support in old rsync versions. Either update to a newer version of Rsync or disable ACL and XATTR support by removing the ''-X'' and ''-A'' options in the bash script, that means, replace ''rsync -aAHXv'' with ''rsync -aHv''. This will disable ACL and XATTR support which menans, such attributes won't be backed up.
