DPM 2010 - Tape Marked for Offsite RRS feed

All replies

  • Hi

    The following three parameters effect offsite-ready, only one of them is configurable, so increase Write-period ratio if you want to use the tape longer period of time.

    When tape colocation is enabled, a tape will be shown as Offsite Ready when any one of the following conditions is met:

    - The tape is full or is marked full. (This includes the I/O 0x8007045D error problem described above.)    
    - One of the datasets has expired.    
    - Write-period ratio has been crossed.

    (By default, this is the first backup time + 15 percent of the retention range.)

  • Thanks for the reply Mike.

    So if all weekly backup jobs have a retention of 4 weeks, the tape will be marks for offsite about 4 days (or 4.2 days according to calc) after the start of the first backup?

  • Hi,

    Yes, with the default write period ratio, so increase that if you want DPM to use the tape for a longer period of time before being marked offsite ready.

  • I would like the tapes to marked for offsite on Monday morning. The backups start 4 am Saturday so would 8% sound about right.

  • Hi,

    I would like to know your reason. You can remove tapes from the library at anytime. They don't need to be marked offsite ready.

  • It was a request from the backup operator. Would you recommend that they change their practises?
