Backups failing with 84 when writting on DataDomain

[ekakshari]

Hi,

We have a setup of OS : Linux, DD : dd990, NBU : 7.6.0.2

When running backups on DD, we are getting failures randomly with below given error in bptmlogs

I think you should open a support case with EMC and let their support check if the error code matches a known defect. A lot of defects in DDOS code is related to Netbackup accelerator - if possible disable accekerator and re-try the operation as a work around.

I agree with Nicolai.

A DataDomain 'plugin' error always points to DD issue.
