Migrating B2D disks to new storage system
Here's my scenario:
- We have a Backup Exec 2010 R3 SP4 Media Server installed on a Cisco UCS blade as a Windows 2008 x64 machine.
- We have a Netapp 3270 storage system.
- The Backup Exec system disks (c: system, d: data, e: page file) are all SAN volumes on the storage, presented to the OS as RDMs so the machine is configued to boot from SAN.
- We also have 4 other volumes on the NETAPP dedicated for B2D (3 volumes for daily incremental backups and 1 volume for weekly full backup).
- All the b2d volumes are presented to the OS as local disks.
- Out daily backups are kept for one week and are than overwritten (Backup job option set to overwrite).
- Our weekly backups are also kept for one week and are overwritten the next weekend (Backup job option set to overwrite).
We're now in the process of migrating to a new Netapp FAS8040A storage system.
For the system disks we're using a script provided by netapp which will transfer the volumes to the new storage automatically.
For the B2D volumes, we do not want to transfer them all to the new storage as they are pretty big and it's time consuming.
Instead, this is what we're planning:
1. Stop the BE services.
2. In the OS, change the drive letters of the current B2D disks.
3. Create 4 new volumes on the new storage and present them to the OS with the drive letters of the old disks.
4. Create the relevant folders on the new disks, as they were on the old disks.
5. Start the BE services.
6. The BE won't feel the difference and will actually backup to the disks on the new storage. I guess that in the GUI I'll see all the B2D files as not present (with the "minus" icon on them)?
7. In case we'll need to restore we'll just Inventory the folders on the old disks.
8. After a week it will be safe to delete the old volumes completely.
Is there anything I'm missing in this plan?
