VNX Snapshot shedule

It is VNX Block snapshot, not snapsure.

Keep in mind the savvol usage and that you cannot shrink the savvol

i have never seen anyone create snapshot for block devices with that kind of retention. Hopefully you can educate your customer that snapshots are not backups,  your monthly retention requirement should be a backup to an offsite media ..not an on-array snapshot.

Thank you for your support.

I don't create the schedule yet.

I  plan following 2 snapshot schedules.

1. daily snapshot with 31 days retention period
2. monthly snapshot with 12 copy with 12 months retention period

I want to know good point and bad point for each schedules.

I would review the whitepaper on VNX Snapshots before you determine your next steps

In particular around P22

You would need to pay f attention of how you structure your pool to handle the IO's required to do the operations you are proposing with

your backup schedules

Also review the VNX VP Release notes P29

Are you talking about VNX Snapshots AKA Advanced Snapshots?

If so, you can do this with AppSync.  However, it only works with SQL Server, VMWare (VMFS) and Exchange.  If you are not running the above you can script snap creation and deletion with snapcli.exe.
