Backup mounted partitions

I've installed partimage and all looks ok so far... just started it up and started to try and backup a partition as a test... it gives me a message saying that the partition I want to backup is mounted so it won't work... it then appears to let me go through and create the image file... I've gone through the documentation and FAQ's and I can't see anything specific about this, but I guess the questions are...

1) Does partimage only work on un-mounted partitions?
2) If I can't use partimage to backup my live production servers (I can't umount the partitions as it's acessed 24*7) anyone got any other suggestions for a tool to use?

Thanks

1) I did RTM but it simply says "Never backup a mounted partition" but makes no explanation of why not...
2) Commercial solutions I know about... was asking if anyone knew any Open Source solutions...

Data Integrity

The key phrase when it comes to making backups is "Data Integrity". If you can not guarantee that the copy of your data is valid, then it is worthless. Data integrity can be compromised in a number of ways. One way is to change the data during the backup.
If you are half way through backing up a live partition, and an event occurs that changes data in a location that you have already backed up, and in a location that you have yet to do, the backup has become corrupt. If you allow the backup to continue, you only have half the changes, and it may get the last half, thus making your backup data distorted.
The easiest way to guarantee that the data on the partition is not being changed before the backup is finished, is to not allow the user to backup a mounted partition.

Just to clearify one thing:
partimage is not meant to do a live backup.
It is meant as a software able to create an image of existing partitions (therefore the name) to do a System rescue restore or multiple installations from a base image(-set).
If you want to do backups, you need a real backup software (if you want opensource look for bacula) that understands timestamps, versioning and (in best cases) does a checksum of the data. Which means a software that can do a full, differential and incremental backup.

So many people overlook this. There is a wide chasm between an image and a REAL backup!

Has anyone had success with using this on the new Windows 2008 Server OS? What about 64Bit Windows 2003?

Thanks
