PureDisk, tape and backup strategy

Steve_Lussiaud

Hello,

 

Netbackup permit to realize the following backup strategy :

  • Weekly full backup done on tape
  • Incremental backup done on a dedup pool

 

I have several questions about this :

Does Netbackup can find modified files between full backup on tape and first incremental backup deduplicated ?

A Full backup deduplicated is not necessary ?

 

Thanks for your answers.

Regards.

Steve

Hi

Netbackup does not write deduplicated images to tape. Deduplication is only kept on Disk.

Netbackup re-hydrates the images when it writes off to tape.

Depending on what your retention is, you may never need to write incrementals to tape at all.

I write FULL off to tape and just keep incremental on disk for between 30-90 days.

Do you know of a document which details the process of vaulting from a puredisk appliance (5020)? 

 

Thanks!

Hello Simon,

I'm ok with you about Netbackup does not deduplicate data on tape.

When you realize your Full backup, you use a normal backup directly to tape, just your incremental are done to disk ?

Right ?

All depends on your data classification and recovery time / options and data types. If dedup is good then send Full's and Incrementals to disk, then rehydrate (full's) to Tape if your offsiting.
