Data to Tapes Not Compressed
I am using LTO6 tapes with the HPE MSL2024 tape library. I am sure the Hardware Compression has been enabled at the tape library level, but the data writing to the tapes does not seem to be compress...
Forum Discussion
Are you backing up directly to tape or to Appliance followed by duplication to tape?
If duplication from MSDP - what kind of dedupe rates are you seeing?
Are you following all the best practices as explained in NetBackup 52xx and 5330 Appliance Capacity Planning and Performance Tuning Guide ? e.g. Turn off Oracle compression while performing backups ?
Do any of the systems that you backup contain a high amount of media files (images, videos)?
Hi marianne,
I am backing from MSDP to tapes, and the dedupe rate is about 65%.
The systems don't have media files. They are mostly the Hyper-V VMs, and some files dumped from RMAN.
I'll look into the Tunning Guide.
Thanks a lot,
Ross
