  • backup exec 10d - backup media size?

    I have an sbs that I am installing Symantec Backup Exec 10d on. I have 5 160GB drives in a raid 5 array. What size backup media do I need? I have no idea how backup exec compresses or anything. Would a 320GB drive be over doing it or not enough? I want to buy two and just swap them every day. I also was wondering if you could fit more than one day's backup on a drive without erasing the old one.

    How much data do you currently have??

    Are you going to be backing up to tape or HDD???

      I'll be backing up to an external HD. When I migrate everything over to the server, I might have 200 GB max on the server.

        Ok.

        You'll need an external HDD that could accomodate the 200GB data at a compression ratio of 1:1. You cannot and will not ever acieve the compression ration of 2:1, or at least i haven't.

        You would then setup a backup job to disk job and away you go.

        SEE HERE

        Also you can fit more than one days job on a single ddrive. You would just set the job to APPEND to the disk.

          I am moving this to the SBS Forum since Steven may have some appropriate input regarding backing up and using Backup Exec 10d on an SBS setup.
          1 1 was a racehorse.
          2 2 was 1 2.
          1 1 1 1 race 1 day,
          2 2 1 1 2

            Since you asked....
            My input is minimal since I no longer see the justification in using BUExec at a cost of ~$600 over the built in NTBackup and wizard. In any case compression on a "pure" SBS just after installation is a ratio of approx 1.1:1 ie about a 10% gain. I have had good experience of restoring from the NT Backup (including Exchange). Moreover, between e-mail retention and Shadow Copy Previous Versions, I see the full back up more as a Disaster Recovery method than anything else.
            TIA
