This product is amazing. Wouldn't use anything else. Implemented it across hundreds of sites now and it's saved more that a few people's rear-ends. Backups every 15 minutes, you can virtual boot the backup images or even have a standby machine running a delayed restore job say every 1/2 hour or so as a hot standby.. AND replicate over the internet, using a standard conenction, to a DR site.
Symantec licensed their engine for Symantec Livestate Recovery / BackupExec System Recovery, but isn't as feature rich as the ShadowProtect suite.
2 thumbs up!
The new exchange product (OEM of Kroll) is pretty good, but Nucleus Exchange Recovery does a faster and better job for 1/3 the price.
