Retrieving Data from Tape Offsite Tape showing as "Suspect" RRS feed

  • Question

  • Hello,

    I am using DPM 2010 i got the offsite backup tape from which i need to recover some data.

    when i install the tape on DPM it shows it as "Suspect" and i am not able to retrieve data from it.

    Why would DPM shows the tape as suspect?

    Is there any third party tool which can help retrieving data from tapes?

    Regards,

  • DPM usually has good reasons for marking tapes as suspect.

    For example I once used a blank tape in DPM which didn't have a barcode label on it.
    All tapes have a chip in them which the drive reads. 
    DPM learned the chip ID and used that to identify the tape. It noted that there was no barcode.

    Later I found an new unused barcode sticker and stuck it on the tape.

    The next time this tape was put in the library, the library read the barcode with the laser.
    The next time DPM saw this tape, it marked it as suspect, because previously it had no barcode, but now it does. 

    If you have an explantion for why DPM might now think something like this happened to the tape, then go ahead an clear the suspect flag.

    Otherwise, maybe someone changed the barcode sticker on the tape and DPM is warning you about this switch.

    Try the tip on this page for changing just the one tape from suspect to not suspect:

    If that's too hard, or you don't care, read this, it just marks all tapes as not suspect:

  • Any 3rd party tool apart from DPM which can retrieve data from tape?
