(pseudo) incremental backup with different exclude lists using hardlinks and rsync
544a7d269e
User may optionally create a file rsync_failure_codes with a newline-separated list of rsync return codes that are to be regarded as complete failure. If rsync exits with such a code, then the backup will be marked for deletion during the next ccollect run (if delete_incomplete). I added documentation for this feature in doc/ccollect.text In my experience (yours may differ), two rsync exit codes that belong in this file are 12 and 255. I have seen 12 result from ssh errors and 255 result from a kernel module conflict. In both cases, the resulting backups were empty. Without the rsync_failure_codes option, such errors cause good backups to be deleted, as per c_interval, leaving behind the new empty backups. In the long run, we may want a different and more comprehensive method for analyzing rsync errors. In the short run, I find this option necessary. |

-------------------------------------------------------------------------------- ccollect.sh, Nico Schottelius, 2005-12-06 -------------------------------------------------------------------------------- ccollect backups (local or remote) data to local or remote destinations. You can retrieve the latest version of ccollect at [0]. ccollect was inspired by rsnapshot [1], which has some problems: - configuration parameters has to be TAB seperated - you can not specify per source exclude lists - no per source pre/post execution support - no parallel execution - does unecessary moving of backup directories - I didn't like the configuration at all, so I used the cconfig style [2]. Please use tools/report_success.sh to report success, if you are successfully using ccollect. Have a look at doc/HACKING, if you plan to change ccollect.
