server backups size

Hi.

I backup a lot of stuff to deduplication storage and to disk storage, they are VM, windows servers SQL DBs and so on. Is it possible to somehow get info about how much storage does all backups take for specific protected server?
I tryed to use reporting, but couldn't construct report to provide such info.
The only way i found is to go diskstorage->order backup sets by resource name->sumarize each backup set size property. It is bad solution and works only for diskstorage backup sets but deduplication backup sets don't have such property.

  • I suspect you cannot do it for deduplication because some of the 'chunks' of data that are sampled by Deduplication might apply to more than one backup job and/or server

    The way deduplication works is we chunk up the data and then compare chunks about to be backed up with existing chunks, if we find a match we increment database records instead of backing it up again (which is how the space reduction occurs)

    Hence how can you run a report that says server X is currently using this much storage when 30% of server Y is using the same storage? (or even the job 2 days later for server X is using 90% of the first job for server X etc)

    Note: unlike things like ZIP compression, which only samples within a single file, deduplication operates across all resources sent to the same deduplictaion folder.

  • Well you could possibly use BEMCLI to script some kind of result into a text file and then manipulate that inside excel

    If you are using one of the capacity licenses then the details of the capacity usage (in the home screen of the BE console) does show you the largest backup in last 30 days for every resource

    Not sure we have any specific report that will add up all the backups of a given resource for you though

      Of course i tryed, but it doesn't have necessary category and fields (advanced fileds) to provide such info.

      Ok, for deduplication storage i understand.

      But is it possible to figure out for server whose backups are on "Disk storage"?
