VERITAS NETBACKUP WITH RED HAT CEPH STORAGE
We are using netbackup with ceph storage where ceph is presented to the media servers as a MSDP. Since MSDP has limitations of one pool per media and a sizing limit of 96 TB, we are planning to use CEPH as a S3 - backup target for the new media servers we have to configure. I want to know if we configure Ceph as a S3 cloud storage, can Netbackup perform deduplication? Will all dedup be just on client server using accelerator or we can have target dedup by netbackup as well?
Or netbackup will send all backup data it receives to Ceph without any dedup, leaving all data reduction to be handled by CEPH?
Can CEPH as a cloud storage perform dedup on its own? With CEPH 4 , we will have erasure coding, so the total storage used will be less but in terms of dedup what advantages can I have by using ceph as cloud storage instead of a MSDP.
If anyone is using Netbackup with Ceph, could you share your approach please.
1) Starting from 8.2 NBU doesn't have 96T limit:
2) >I want to know if we configure Ceph as a S3 cloud storage, can Netbackup perform deduplication?
I think that NetBackup CloudCatalyst will help you. Read about it and it will help you to understand the place of deduplication.
3) >Can CEPH as a cloud storage perform dedup on its own?
You may try to deploy Ceph on VDO with deduplication but I don't have such experience in the Enterprise environment
