Do we have any option to include expiry time while taking manual snapshots for volume. If there is no expiry time for manual snapshots we take daily it may pile up and unnecessary space is consumed.
Each snapshot has an expiration date and time, when it is deleted automatically.
You can remove a snapshot manually before its expiration, or you can preserve a snapshot to prevent it from expiring
So Scheduled snapshots will delete automatically and if you are creating snapshot manually mean you can have the snapshot as long as u deleted manually from the system.
Here my answer is NO in terms of following way
1) Manual snapshot can be taken by giving some command from mapr CLI
2) Once any snapshot is created on the specific volume which is scheduled we can place expire time for it.
From the MapR documentation and admin course
"You can create a snapshot manually or use a schedule to automate snapshot creation. Each snapshot created by a schedule has an expiration date that determines how long the snapshot is retained. When you schedule snapshots, the expiration date is determined by the Retain parameter of the schedule."
So if the snapshot created with schedule option can set to expire time .
Read the terms clearly in the below documentation from MapR
Working with Snapshots - MapR 5.0 Documentation - doc.mapr.com
For your doubt
"If there is no expiry time for manual snapshots we take daily it may pile up and unnecessary space is consumed"
That why Administrator has to check the snapshots weekly and to delete old or unnecessary snapshots from volume directories.
Snapshots don't take much storage unless user keep on modifying the data storing in volume.This is the concern you have to take care of
Thanks for the information . But Note you mentioned is our situation. we have more data alterations going on all time.

Thanks for your responses. do you think including snapshot expiry time as part of manual snapshot is a reasonable argument/idea . Any insights ?
