Greetings, I wanted to share a script that I created that allows you to get generalized de duplication data from a Data Domain on a per client basis. I thought it might help out folks in the community.
I have found it very helpful in finding clients that don't dedupe well, especially oracle encrypted/compressed backups.
As with any script of this nature, your mileage may vary. It works on solaris 10 with DDOS 5.2.x. The directory structure between DDOS4, DDOS5.0, and DDOS5.2 are a little different, so they will not work on the prior version. If people are interested I can post the changes you'd have to make for those versions.
This script does rely on the binary dos2unix which is available freely.
You must also have a shared key between the host you run the script on, and the data domain you are querying. It must be passphraseless, so you don't get continually asked for a password.
Feel free to make suggestions to improve the script, sometimes I'm kind of a hack.
The usage is scriptname.ksh FQDNofDD LSUname
