First i have lv0001 shared, and put some files on it. Then i started scheduled (10min interval) snapshot snap00001 and share it, and all files was copied to snapshot. But when i change something on lv0001, there is no changes on snap00001 (regardless of time). Also snapshot share is accessible for writing (even if i set 'read-only' on that share). So, what's purpose of interval snapshoting? How it works? Thank you.
When you want to schedule a Snapshot and have it accessible in "Read Only" mode please do the following.
Create a Snapshot in Volume Manager and assign it to the Logical Volume
Create a Share for LV0001 for your data located in CONFIGURATION > NAS RESOURCES
Create another Share for your snapshot "Snapbackup" located in CONFIGURATION > NAS RESOURCES
Set your share "Snapbackup" for read only located in CONFIGURATION > NAS RESOURCES
Then set your time values for the Snapshot in MAINTENACE > SNAPSHOT
Note: This will not be a continuous Snapshot for the Logical Volume only for that point in time or until the next scheduled start time.
