ALL,I have a requirement to STOP the CACHE DB ,take a snapshot using NBU VMWARE policy type and backup the data from snapshot and START the CACHE DB once the snapshot is taken.Since i am using VMWARE policy type i cannot use the bpstart & bpend scripts to start and stop the CACHE DB as there is no NBU software on the client to place these scripts.Master,Media and client are on NBU 7.7.3 versionIs there a way this could be achieved while i could still leverage the VMWARE policy type.

Assuming we are talking about a vm hosted on vmware, you can use a pre freeze and post thaw script to control cache.

Best practice to backup CACHE DATABASE residing on a VM

ALL,

I have a requirement to STOP the CACHE DB ,take a snapshot using NBU VMWARE policy type and backup the data from snapshot and START the CACHE DB once the snapshot is taken.

Since i am using VMWARE policy type i cannot use the bpstart & bpend scripts to start and stop the CACHE DB as there is no NBU software on the client to place these scripts.

Master,Media and client are on NBU 7.7.3 version

Is there a way this could be achieved while i could still leverage the VMWARE policy type.

If this is the same type of caché database we are talking about, you can use the following commands to let caché know you will freeze and thaw:
cache -s. -U%%SYS ##Class(Backup.General).ExternalFreeze()

cache -s. -U%SYS ##Class(Backup.General).ExternalThaw()

We have CACHE on AIX, and we snap using our storage. Granted we only have 4TB and 6 TB of data, but it is spread over several file systems. Since we set up each data set as a seperate LUN, we can snap them and mount them on a different server, then back up from there.
We are moving to Linux VM, but I think will will be retaining this config, so we have ease of backup and restore.
Plan A for DR does not use Netbackup, we recover from storage/snap, but we do the backup to tape for retention purposes. And we have a shadow server that we repopulate using restore.

  To clarify - we use a controling script outside of netbackup to stop and clone and restart CACHE, then mount the cloned/snap disk on another server, the data is then backed up from there using schedules.

  Thank you for the info.In my case the customer wants Netbackup to stop and start the CACHE so i would go with the below option
