NDMp backups are fail as maximum number of dumps/restores allowed is reached for a filer.

Hi All,

We are using Veritas Netbackup to take NDMP backup on a netapp filer. The backups were working fine since last few days. Recently, backups are started to fail with below error.

NDMP_LOG_ERROR 1 DUMP: Maximum number of allowed dumps/restores (4) in progress

We have a setup where 6 jobs for same filer will be running together. Because of this issue we had to change limit to 4 to avoid failures. However, this is impacting on time to complete backups. Is there anyway we can change limit for a filer?

Thanks,

Deepak
