So backup up an ISO image would speed backup times because it gets the entire disk blob from the IFS.
Isn't an unmounted UDFS also the equivalent of a disk blob (think the old Windows File Server IOP) so backup of that would be similar to backing up a disk blob ?
I would think the main benefit being that the tape can stream at full speed because it's backing one large object rather than a bunch of individual objects.

An ISO is merely a file on the file system no different than any other file, except for the contents.
An iASP is really a UDFS and is "mounted" when the backing device is varied on.
You can back up the UDFS directly but then there is no file level recovery.
Most folks will just back up the iASP along with the balance of the IFS. In this case that would be foolish. I would have a tape that I initially backed up the iASP with, then build incremental saves of only new objects on the same tape. BRMS would do this nicely for you. Then recovery of a single object would be simple. Clearly the save would be very fast as well.
Remember, to access the iASP IFS file system you only have to use the iASP name in the path, so a directory Agile, with file Source would be addressed
like: /myiaspname/agile/source. (Assuming the iASP is varied on and
available)

Hey Jim,
Do you know if an iASP would be considered a disk blob similar to the way a disk based ISO image is ?
If that's the case, then backing it up should be better than backing up individual small IFS files.
Nobody seems to be able to answer this question for me.
Thanks

Then you need to rethink the process. Sure that's absolutely safest, however how long will it take? What is the chance of issues with only adding new? Down time is getting harder to get, and if the backup/restore fails for some reason and it has to restart you've just bought a whole bunch more down time.
I used to think image catalogs were not worth the time, now I can't imagine working without them. I used to think PuTTY and SSH were for Unix, now I'm
on IBM i more than half the time with SSH via PuTTY. When Mike Pavlak
started the whole PHP thing on IBM I many years ago, I never thought open
source languages would ever catch on, clearly I was wrong about that. The
point is: "We've always done it that way" is one of the poorest excuses in business and you partner has to start thinking about your needs not the
safest, easiest way to do it. Oh and by the way, that also adds lots of
billable hours to the process, as an added bonus to the partner.

In the past, our BP has always done another full restore for the actual cut-over.

Before I forget - we are on V7r3
When I use STRSQl with the following command Select Cust# as
Customer_nbr from File01 where FieldB = 'SOMEVALUE'
Data is displayed, with the column heading Customer_Nbr
When I run the same query AFTER pressing F13, choose 1. Change session
attributes Change SELECT output to 3 (for File) and define a file name
The file is created, with the field Customer_Nbr
However, when I change the query to the following Create or replace
table qtemp.allcusts (Select Cust# as Customer_nbr from File01 where
FieldB = 'SOMEVALUE') With data I get the error Token CUSTOMER_NBR was
not valid. Valid tokens: ( ROW IDENTITY TRANS And the cursor is under
the C of Customer_nbr
Anyone any idea what I am doing wrong?
I could be incorrect, but I don't think it is supported to rename the columns of a subquery from within the subquery itself.

subject: Overlay rotation problems
I am creating an overlay from an image that was provided by a customer.
The image canvas size is 8.35 X 7" I am using 8 1/2 x 14 page size, and am
placing the overlay offset at 7" down.
When I print the overlay to the AFP driver and try to print it on my page,
it's rotated 90 degrees. I'm not using any page rotation on the spool file.
I do this all the time but I'm stumped. Any ideas? Thanks

Diego, I've tried to have VIOS as a guest for vscsi and it's never worked,
the GUI doesn't let you set VIOS as a vscsi client, only server. Maybe the
enhanced gui does? I haven't tried it again.
Jim, the problem lies in that the network install is really a NIM install,
that uses an ethernet adapter local to the LPAR an therefore doesn't go
over the FSP link between HMC and POWER machine.
Best Regards,
Roberto

This is completely different than StorWise. If you follow IBM instructions
in building the USB device, it works well.
How can a network issue come into play when the HMC has a solid Ethernet
cable from the HMC port to the HMC? Now if you are running that connection
over a LAN and it's not in its own completely different network than any
other traffic, then we have some other items to discuss regarding security
and a host of other things.

You can install 1 VIOS from HMC (image repository), and then create the
other as gest to the 1st VIOS, but you must be quite sure this works.
Any small network issue and you are in big trouble.
With a DVD drive you can ask your H&E to insert the media and that's it.
Haven't tried with USB thumb drive, but I don't feel comfortable using
them.
I still remember first Storwize with SPECIAL usb pen drives, and HMCs with
STEC pen drives...

If they outsource recovery, upgrades, etc, that's one thing. But if
