Re: VNX for file - nfs - snapshots
If they are snapshots created by the replicaiton job, I'd expect their timestamp to change every 1 minutes or so, but it does not.
The timestamps would only change every minute, if there is data to be copied to the destination and if the amount of data to be copied to the destination could be finished in one minute.
You can check the checkpoints doing a
fs_ckpt fsname -l -a on the controlstation. Typically the first 2 with the name beginning with "root_rep_ckpt" belong to the replication session.
Verify this output with the output of the linux client (ls -alt)
