Backup TIFF Files RRS feed

  • Question

  • Hi All,

    I'm implementing DPM in my environment, but I wonder if the DPM has sufficient performance to backup millions of TIFF files.

    Currently, my environment has more than 270 million of TIFF files, each with size of about 60KB which is stored in an EVA storage.

    My intention is to back up disk to disk and then use another tool to put on any tape.

  • I think if the churn isn't that high, you won't have any performance issues besides the initial replica.

    So create that initial replica manual, and you should be fine.

    Cheers,

  • Hi,

    First, yes, DPM should be able to do this.  There is a but... :-)

    270 million of files is a lot :-), do they change a lot?  What is the data churn on a daily base?  If it is not that high, then there will be not an issue at all.  (You work on EVA so...)  We are talking about approx 15 to 16 TB (if I calculated well) so a DPM server should be able to do that.  I do think however that maybe a dedicated server will be necessary but that will depend on other variables.

    The initial replica will cause you probably issues.  Not that it is going to fail or so, but it will take time... A LOT OF TIME, so plan carefully to do this outside business hours and preferred weekend or so (or do the manual creation or the initial replica)

    Just my 2 cents,

    Cheers,

  • Hello Mike, I got it, but I'll have trouble with the performance, right? Other tools give me a transfer rate of about 15MB which is very little. Is not it more beneficial I think in another form of backup? To answer your question, these files do not change much. At best they are replaced. Regards, Severen
