Some basic questions

Hi

Sorry in advance if this is really stupid. I have recent;y just got my first iSCSI SAN and it had Starwind CDP preinstalled on it. No CD's, manuals or anything else...right now I just have a couple of basic useage questions please.

The SAN box has 16GB RAM currently.

1. Once a target has been created, is it possible to edit some/all of the settings? I cant seem to find a way to without deleting the target and recreating.

2. I have created 8 targets so far, and I allocated each target writeback cache of 2048MB. Right now most of those are empty and doing nothing, yet memory utilisation is at 92%. Is this normal? Or will I be screwed when this goes into production and users are actually using these targets properly?

3. How does Starwind CDP work??

Hello

1) For now it is possible to extend the size of image file target only
2) It depends on how much RAM do you have, but I`m assuming that there is somewhere around 16 Gigs, right? In this case its normal.
3)CDP replicates block level changes in real time, for zero data loss, when replicating off site. Unlike traditional backups, CDP allows you to restore data to the time immediately before data corruption or application failure for minimizing recovery point to seconds vs minutes or hours. CDP replication saves disk space at the disaster recovery or backups site since it only replicates changed blocks, not entire files.

Hi

How do I extend the size of an image I have already created?

How do I use CDP to rollback?

Go to Device tab, right click on the device, and you will see Extend Image Size string.

If I go to device tab, the only thing I can right click is the Device name with options to Remove, Force Remove, or Create Snapshot?

So it's not an image file target - It's a snapshot device, this changes everything.
