With vg00 at 38GB, it appears normal so far.

It depends how big your vg00 is and what tape drive you are using.

Your vg00 looks unusually large at 38GB. Do you have nonOS software installed under vg00? Unless you intended it that way, you should dedicate vg00 for OS only and use vg01 etc for add-on software and data. By the same analogy, igniteUX is typically for vg00 backups and OS recovery and your standard backup software (fbackup, netbackup, omniback, dataprotector) for add-on software and data.

Thank you for reply.

vg00 is having application installation dump size of 27GB.
vg00 is 146gb OS disk. it is having 13 lvols.
tape drive is DDS4.
does this spec consume 3 hours?

DDS4 and 38GB may take upto 4 hours.

Best result I've ever seen is an ignite backup in 7min.
This was on a fiber connected tape drive on an idle system.
The speed of the tape drive is the most important regarding the backup time for ignite (and of course the data size...).

9GB of vg00 to ultrium2 takes about 30 minutes.

27GB for app installtion binaries is alot.

Might want to think about excluding it and using another method to back up the application. Ignite works most reliably when used only for the OS.

We had one server here that an Ignite (of just vg00) took over 13 hours on Ignite Ver 7.2.94. This server has over 6,000 disks that were taking a long time for Ignite to verify. We were advised to upgrade to 7.4.157 which had some fixes to improve the search. Now Ignite takes 1.5 hours on that box.
