-------------------------------------------------------------------------------- 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.
