Hi,

We have configurd the NDMP backups and when the backup schedule starts, it will create too many snap sure checkpoints as shown in below example.

We are using NAS700 runing on 5.6.52 code.

There are 4 stream avaialble to take the NDMP backup but when the backup started, only on one stream the throughput  will be seen and the other 3 jobs will be in waiting state. When the 1 job completes, teh backup of 2nd job will start.

Is this behaviour on the backup because of the  checkpoints? We are using Commvault backup
