We are in process of configuring backup for NDMP volumes that is configured with snapvault.

We are planning to configure backup for those volumes as windows CIFS backup.

First copy : “primary snap” that will create a snapshot on the source. (Intellisnap enabled)

second copy : AUX copy will be triggered that will replicate the snapshots to snapvault target

Third copy : Backup copy to disk library ( source copy : snapshot on the snapvault target)

Fourth copy : selective full to tapes  ( source copy : third copy)

My query is, since second copy will be vault/replica copy to replicate the snapshots to snapvault target.

Do I need to configure Full backup or Incremental is supported ?

I tested a backup with daily Incremental schedule and Synth full schedule weekly once. and noticed AUX copy did not ran for that subclient for incremental backups. However, If I trigger a manual full backup , vault/replica copy runs fine.

If I try to run AUX copy manually for Incremental backups, it says no new jobs to run.

If, only Full is supported for vault/replica copy, it would mean during backup copy to disk, it will run a full backup every day.

Can someone please help me confirm if Incremental is supported for Vault/replica copy  ?

I am not sure if I am missing something here.

Additionally, my understanding is synth full is not supported for NDMP but it is supported for windows CIFS backup . Is this correct ?
