What is consistency point snapshot?
Do we able to access that snapshot?
Thanks
A.Saran
Solved! See The Solution
Consistency Point:
a CP is triggered whenever the Filesystem reaches a point where it wants to update the physical data on the disks, with whatever has accumulated in Cache (and was journaled in NVRAM).
Snapshot:
a SnapShot is created whenever the snap-schedule is configured to trigger it or any other operation (SnapManager, SnapDrive, SnapMirror, SnapVault, Administrator) creates a new SnapShot. Creating a SnapShot also triggers a CP, because the SnapShot is ALWAYS a CONSISTENT IMAGE fo the Filesystem at this point in time.
You can access a SnapShot by many ways, e.g. mapping the network driveletter to a CIFS Share and then change into the ".snapshot" directory (or ~snapshot).
You cannot access a CP, because this is a process happening internaly in the filesystem.
Hope this answers your question,
Peter
Its not a snapshot. Its a CP created when triggering a snapshot.
What was the diff b/w snapshot and consistency point?
