    Migrating to a new Server

    Pierre Devereux Level 2

      Hi,

       

      When we started a few years back, we used an old XP workstation to house a 2TB disk that we used as our Data storage. After a while, (a long while in fact ) The 2TB was filled, and we installed a second 2TB drive. There were now 2 shared drives on the network, each presenting its own file structure. This, in turn, was backed up to external 3TB drives for our backups. Since we started proper, Data has started growing properly as well, and the second 2TB drive is filling up. As a result, the location for backups is no longer sufficient, and we have bought a NAS device and a DAS device. The NAS currently has 4X3TB drives installed, and the DAS has 3X2TB drives installed.

       

      I would now loke to migrate all the data from the two drives in the old XP machine accroess to the one partition presented by the NAS device. What is the best way to do this, as I am assuming there will be a lot of file location issues with AE when moving its source data around?

       

      Also, as an aside, I am trying to figure out the best solution for the new devices - I have the following options:

       

      1) 2X6TB partitions on the NAS device - using JBOD (or spanning)

           a) Use partition 1 as Data source - no redundancy

           b) Use partition 2 as a backup source - either live daily copy-type backups, or Acronis file level backup

      2) 1X6TB partition on the DAS device used as weekly backups (with daily incrementals) - this backup device would be used for roll-back purposes, in case corrupted data gets backed up on the NAS

       

      The other option, is:

       

      1) 1X6TB partition on the NAS using RAID1+0 for striping and redundancy.

           a) If a drive fails, we have the oppurtunity to replace it on the fly, and now having a live "Backup" in case of single disk failure (Double, if each disk is part of one mirror set)

      2) 1X6TB partition on the DAS device used as weekly backups (with daily incrementals) - this backup device would be used for roll-back purposes, in case corrupted data gets backed up on the NAS

       

      The final option I can think of is:

       

      1) 1X6TB partition on the NAS using RAID1+0 for striping and redundancy and enabling volume shadow copy for roll'back file recovery

           a) If a drive fails, we have the oppurtunity to replace it on the fly, and now having a live "Backup" in case of single disk failure (Double, if each disk is part of one mirror set)

           b) 1X6TB partition on the DAS device used as weekly backups (with daily incrementals) - This will then be an extra backup for complete hardware failure of the NAS device.

       

      Any suggestions would be welcome - thanks guys

          Hi,

           

          COme to think of it, Scrap the Volume Shadow copy - We are not running off a microsoft server. so that wont work!

            In a scenario such as you describe one wouldn't bother with manually organizing data. You hit the red button on your data management/ backup software and let it work out the details. Generally one would also use RAID 5 for critical file servers since even while it's running specific single files may need to be restored on the fly if a write operation fails. This also eleiminates the need to run a "full backup" server since it will be extremely unlikely that the server will suffer a catastrophic failure and you lose all data. If that's not an option, a RAID 01 seems more appropriate for your situation than a RAID 10 since you deal with large files and would ned to maintain their integrity at least within one of the stripe sets or else your backup plan falls apart.

              Hi Mylenium,

               

              You not at NAB?

               

              Thanks for the feedback - around the Data migration though, Will AE not have a problem, as the file locations will change? From 2 different server shares, to one new server share?

                If the folder structure is consistent AE should not have any issues finding its files, since paths are stored relative to the project. Only absolute paths that point outside the AE project's sub-folder might be an issue, but even that can be remedied with a replace file operation and AE auto-scanning for the rest. And naturalyl you could just avoid it entirely by mapping the shares back to the original setup - after all, they are just virtual file paths.
