Disk based backed and Tape
I ahev followign questions.
We are planning to add disk based backups to retain onsite backups in a deduplicated format.
Proposed Setup: 24TB(RAID 10),64GB RAM, BE 2014. The storage will be local to the server i.e it is not direct attached.
Backups Clients: 4 Linux servers, 1 Ex2010 DAG, 3 Windows servers
Q1: When the data is deduplicated, on the disk. Can the copy job to tape be NOT dedup information? We want to write a FULL backup to tape and not deduplicated data. I haven't testedt his yet. If so what kind of disk to tape job should be created?
Q2: Anyone using RAID5 has seen decent performance with disk based backups? The parity bit degrades the performance, but on a large array wondering if that is a matter.
Q3: My disk based backup doesn't qualify as pure disk or OST certified. Can I still perform client-side deduplication? I tried to do it but got a email statting "Client-side deduplication is enabled for this job, but it could not be used. "
