Archive unit used like tapes
I am trying to use the unit like I did with our old tape drive. I take a set of disks home every night. At the moment, I am using one set of disks. I put them in the unit in the morning, archive the incrementals, and take them home that night.
Do I need to fill the hard drive slots at night?
I know I am being silly but having the open drive bays makes me a little nervous. The server room should be clean so contaminants should not get in there.
When an archive runs it create a device which utilizes all disks in the archive unit. So, you should not leave drives in the archive unit that you do not want overwritten.
Regarding the open drive bays, this should not be a problem. If a problem should develop, the hardware will be covered per the terms of your support contract.
Thanks for the reply. I figured it would be OK. I definitely hope a problem does not develop
We have the Recovery Archive unit which has 4 drive slots. I was under the impression the archive unit only archived to the drive in the 1st slot. Under what circumstances would the archive unit use the other 3 drives in the other slots? I have been leaving them in there to house them.

I am new to the Unitrend backup appliance and archive appliance - so I am learning and getting adjusted after using backup tapes for so long. Sorry for the ignorance.
Can you clear it up for me? Thanks!
Cheha - Couple of things you need to know:
-Every drive bay on the Recovery Archive that has an eSATA cable connected to it from the DPU and a drive is inserted into that slot on the Recovery Archive, will have a piece of the archive written to it since the archive will be spanned across those connected ports.
-At the same time, you can have eSATA cables connected to all four eSATA ports on the Recovery Archive but if you have only one drive inserted then it will only be written to that one drive.
-DPUs are sold with only 1 eSATA port by default, the 4 port eSATA cards are sold separately to allow taking advantage of all 4 bays on the Recovery Archive. It is then possible for your DPU to only be able to connect to one slot on the Recovery Archive and in that case, it would be safe for you to have your stand-by drives inserted into the non-cabled slots because nothing will be written to them.
I hope this helps. Thanks.
It would be nice (feature request) if the option to make a "recovery archive array" was a user-toggle. My data fits on a single drive with room to spare, it would be handy if I could leave other drives in the unit and have the Archive process cascade across disks, only writing to a new one if the first one was full or had protection turned on.
It's annoying to have to remember to swap archive drives or plug in a different one.

I agree and second the motion. I was under the impression that it would work that way. It seems like it should be some type of configuration change that would prevent it from RAIDing the drives on the controller.
