Hello.   The base volume will always contain the current status of your data.  When you first take a snapshot, there is no changed data.  So the snapshot size is zero.  As you write data, new data goes to a new page, and the snapshot reserve is used to keep that old page "alive" by use of pointers.  Deleting a snapshot means pages that are unique to that snapshot, not shared with another snapshot, are returned to the snapshot reserve.   Re: Error message.  There are no errors b/c it's up to you as admin what point-in-time snapshot is most critical.  There is no inter dependency between snapshots.  It's not like a differential/incremental backup where you might need all the pieces for a full restore.    E.g.  You create a volume, and start writing to it.  At 10am you create a snapshot, then 11, and 12pm.   You decide to delete the 11am snapshot.   All that means is that you can't restore data from 11am.  10am and 12am are fine.  The snapshot would has that volume exactly how it was at 10am.  So, in this case it probably would be better to do snapshot every two hours.     If you have to keep them, then you'll need to sacrifice more free space.   The error is coming from the scheduled snapshot task.  Disable/enable should not have any affect on that.   Regards,  Don  
Hello,i examined how EQL snapshots work (AoW), and think to have understood that snapshots are child only to their base volume. Nevertheless, they just store the modifications in relation to the previous snapshot...That's why i'm in doubt it would o.k. to delete intermediate snapshots?The system let me do so, but now i receive [ID: 4.18] ...Could someone please elaborate on this?Thanks in advance
