Thanks Azhrei
We're using a JBOD at the moment so it's a raid configuration of sorts.

My colleague is using a program called robocopy (similar to rsync) to get this ever changing data over to another disk (as a kind of resilience option). I've pointed out to them that there's a purge function in robocopy which will copy all the files that have changed, and also delete files that need deleting.

However, they are convinced that this particular feature is somehow cursed and we'd be at risk of losing all the data!

Therefore, I need to prove to them that, over time, their method could well be degrading the disks.

Convining them to use the 'few files at a time' is extremely difficult and they're set in their ways at the moment!

NAME
backup-manager-purge - backup-manager's wrapper for outdating files SYNOPSIS
backup-manager-purge [TTL] <options> DESCRIPTION
backup-manager-purge is the only authorized entity that can say if an archive should be purged or not. Any tasks used by backup-manager may have to know if an archive is deprecated (eg: the purging phase of an upload method). This tool is here to fulfill that need. Given a time to live (TTL) and a list of archives, backup-manager-purge will return another list of archives, corresponding to the ones that are outdated by the TTL. REQUIRED ARGS
--ttl=time-to-live Specify the time to live (in days) for the archives. Any archive that is older than ttl days will be outdated. OPTIONAL ARGS
--files-from=file A file containing a list of archives to parse, one archive per line. If this option is not used, STDIN will be used for catching the files to parse. RETURN
backup-manager-purge will return the list of outdated files on STDOUT, one file per line. ERROR CODES
If an error occurs, it will print the error message on stderr and will exit with an error code greater than 0. Here are the possible error codes: bad command line (wrong arguments) : 10 internal error (should be reported as a bug) : 20 SEE ALSO
