A press release went out today about IBM’s TSM 6.2. Among other things, it says that TSM now has source dedupe! As big as that news is, there’s another piece of news that is even bigger.
The press release said that not only does TSM 6.2 have source dedupe, it is available in all versions of TSM 6.2 for free! (TSM’s previous server-side dedupe was only available in TSM Extended Edition.) That’s right, TSM’s source dedupe is available as a standard configuration option on any TSM client. Nice.
In addition to source dedupe, TSM 6.2 adds the following features. I’ve put them in the order of coolness according to me. 😉
- Simultaneous backup, migration, and copy active-data operations
- The press release says that “the windows for data migration, storage pool backup, and copy active-data can be combined into a single operation.” I didn’t get a briefing prior to this press release, but if I understand this correctly, this is huge. First, I’m already a fan of the active-data pool, but the problem with it was that it was yet another copy operation. Now the copy of backups to the copy pool, the migration of disk backups to tape, and the copy of active data to the active data pool can be done in a single operation.
- Again, if I understand this correctly, this means that they have functionality like NetBackup & CommVault’s Inline Tape Copy feature where they can copy from one backup to several disks or tapes simultaneously. If this is the case, this is a huge benefit to TSM administrators, who have historically really struggled with the number of hours in the day. This should save them several hours.
- It would be nice if a reader would clarify this one way or another.
- Automatic client deployment & update for Tivoli Storage Manager backup-archive clients for Windows
- I think this is a big deal. TSM has historically required touching every backup/archive client every when you installed or upgraded the client software. TSM 6.2 now supports automatically (via scheduled policies) installiing or upgrading its client software on Windows.
- Expanded use of in-flight encryption
- In-flighyt encryption using SSL has been expanded to Linux, Solarix, and HP-UX platforms.
- Enhanced support for virtualized environments
- TSM now supports discovery of VCB (which you should really be moving off of ASAP), the vStorage API in vSphere (which you should be moving to, as long as you address the snapshot issues), and Hyper-V VSS-enabled backups.
- Faster backup of Microsoft Windows environments
- Prior to 6.2, TSM performed a full backup of the system state of Windows every time it backed it up. Now it only backs up the parts of the system state that have changed. Since the system state has gotten bigger and bigger, and very little of the system state changes from day to day, this should help a lot.
- Updated SAN support
- Although they don’t explain what updates were made, TSM for SAN 6.2 was updated to exploit enhancements in the TSM core.
That’s quite a bit of stuff for a “minor” release. Dude, I would have called it 7.0. 😉
