You should run it when your Full backup and your Base backup are too different. (Most of the time after a system upgrade). The Full backup should print how many files/MB were used from the Base job. If this number is ok for you (and over the time), you don't need to run a new base job. > what about base job retention time and recycling ? > do i need a special pool having longer retention time ? > i assume jobs are incomplete if base job is recycled > before his children. Yes, you need a longer period, it's like Incremental/Diff over Full backups. > what about base jobs and copy, will base job copies work > like all other copy jobs ??? Copy jobs should work with Base jobs, but if you purge a Base job used by a set of jobs, I don't think that the upgrade process that choose the next Copy to make it a normal Base Job will update the BaseFiles table to change all references. It will certainly be a new feature for the next release. If you use copy for emergency, you can certainly update references by hand for the moment, tests and feedback are welcome.
