DPM Short to Long RRS feed

  • Question

  • Problem1:

    Hello,

    My understanding with DPM 2010 has gone out the window this morning. We have four PG's and three PG's have Short Term and Long Term settings applied. We keep data for 5 days on our ST and 3 Weeks on our LT using three seperate Tapes (Disks with Firestreamer).

    An example of one PG which has made me question DPM 2010.

    PG1: (SQL)
    ST. Every 1 Hour, Express everyday at 20:00.
    LT. Every Friday at 07:00

    After checking our tapes (Disk), it appears we have run out of space, (which is another issue I will bring up shortly) checking the Tape it appears PG1 has never performed its LT 07:00 Job, however seems to have the ST backups on the LT Tape. On that Tape we have a backup everyday 20:00 on Tape. Why is this on Tape when its on the ST settings, and not on Short Term Disk?

    I thought it would get transactional logs (SQL) every 1 hour, then every day at 20:00 create an express backup (still on ST)... Then every Friday move the last express with latest transactional logs to create its Friday LT backup?

    I'm very confused by this.

     

    Problem 2:

    Expired Tapes are not overwritten unless I manually mark them as "Free"?

     

    Problem 3:

    Compression is turned on for SQL backups, however no compression is taking place on Tape? (Cannot confirm if Short Term Disk is compressing)

  • Hi Andrew,

    The LT backup scheduled to run @ 7 PM on Friday should use the last Express Full created by the Short Term. In this case, the ST Express Full created on Thursday.

    As a side note I would recommend post these other problems on its own thread so people can benefit while searching the forum....

    Problem 2. Thig might need more investigation as expired tape should be rewritten by DPM.

    Problem 3: Compression only works for backups written to tape or over the wire transfer.
