More on DataProtector 6.10

| 1 Comment
We've had DP6.10 installed for several weeks now and have some experience with it. Yesterday I configured a Linux Installation Server so I can push agents out to Linux hosts without having to go through the truly horrendous install process that DP6.00 forced you to do when not using an Installation Server. This process taught me that DataProtector grew up in the land of UNIX, not Linux.

One of the new features of DP6.10 is that they now have a method for pushing backup agents to Linux/HP-UX/Solaris hosts over SSH. This is very civilized of them. It uses public key and the keychain tool to make it workable.

The DP6.00 method involved tools that make me cringe. Like rlogin/rsh. These are just like telnet in that the username and password is transmitted over the wire in the clear. For several years now we've had a policy in place that states that protocols that require cleartext transmission of security principles like this are not to be used. We are not alone in this. I am very happy HP managed to get DP updated to a 21st century security posture.

Last Friday we also pointed DP at one of our larger volumes on the 6-node cluster. Backup rates from that volume blew our socks off! It pulled data at about 1600GB/Minute (a hair under 27MB/Second). For comparison, SDL320's native transfer rate (the drive we have in our tape library, which DP isn't attached to yet) is 16MB/Second. Considering the 1:1.2 to 1:1.4 compression ratios typical of this sort of file data, the max speed it can back up is still faster than tape.

The old backup software didn't even come close to these speeds, typically running in the 400MB/Min range (7MB/Sec). The difference is that the old software is using straight up TSA, where DP is using an agent. This is the difference an agent makes!

DP 6.0, and possibly even 5.5 support ssh as the install mechanism. You just need to set the appropriate flags in .omnirc on the installation server you are pushing from.
