[Feature Request] Tape Server Caching

[inecula15]

Hello,

We have a Tape server for transferring backups from the linux server repository to the tape library with LTO8 drives.
We want to upgrade the repository server with interfaces up to 100 Gbps.
We need the option to use tape server caching, that stores data on a fast disk before writing the backups to the tapes.
This will help us to improve transferring the backups to tapes.

Thank you!

Hi inecula15,

Keep in mind that the theoretical maximum speed of LTO‑10 is far below 100 Gbps, so adding a 100 Gbps interface may not improve performance.

Regarding your request, you can already configure a similar setup using backup copy jobs.
Add local disks to your Tape Server, set it up as a backup repository, and use a backup copy job to send backups there. Keep these copies for only a few days. Configure your tape jobs to write those copies to tape.

This addresses your request "stores data on a fast disk before writing the backups to the tapes".

Best,
Fabian

Hello Mildur,

Thank you for your answer!
We are using a Tape Library with 10 drives that are writing backups simultaneously - from repositories to the tapes.
Also, we have a lot of data (aprox. 100 TB/week - a lot of backup jobs, hundreds of servers) that are transferred daily to the tapes and we can't use another backup repository (for backup copy jobs).

Best regards,
Ionut

Hi inecula15,

Would you be able to share a little knowlegde about your tape server since you added a 100Gbps NIC.
How many drives are you able to keep running on that tape server ?

I am trying to size a solution a little bit bigger, and would like to get some real live numbers.
