We Often Loose Data. If we, there is a failure and the recovery of the dedupe becomes tedious. To protect and recover dedupe in case of failure, below information would be helpfull
Protecting Dedupe:
1. Dedupe device Can be backed up as it is Using backup exec Using the Shadow Copy Components
its simmilar to the DFSR backup (Shadow Copy components -> Userdata -> backup exec Deduplication storage)
You will backup the configuration and the storage when Its backed up using the shadow copy components.
2. In ase of corruption you can restore the same back again to make it working.
As easy as that.
The rest of the Things are:
>> Exclude the dedupe device from AV scanning or any other third party access to the folder as that might corrupt the Data and links.
>> Have a Dedicated volume(probably a disk) for the Dedupe To avoid I/O bandwidth.
>> Phyisical memory is a factor wich affect the performance of the Dedupe and the CPU.
A Quadcore Processor is necessary to drive the dedupe
