VNX Snapshot shedule
We are about to create schedule for VNX snapshot.
Could you tell me each good point and bad point?
- daily snapshot with 31 days retention period
- monthly snapshot with 12 copy with 12 months retention period

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.

Ok – you still need space there.
Keep in mind that by using snapshots you are getting performance characteristics like thin LUNs.
Some flash drives in the pool for the metadata help a lot there
How do you create a schedule with VNX block snapshots?

Thank you for your support.
I don't create the schedule yet.
I plan following 2 snapshot schedules.
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.
