HP-UX used to come with a filesystem called jfs built-in and an option called 'Online-JFS'. I believe that in recent years this HP re-engineered version of Veritas has been replaced with straight Veritas vxfs. Under Online-JFS and under vxfs with some add-on there was a feature which allowed the fast creation of snapshot images of mounted filesystems. The best backup solution I ever came up with for a client of mine on HP-UX with UniData was to initiate a dbpause (which takes a few seconds), create a snapshot of the live database filesystem (another 20-30 seconds), and then issue a dbresume (almost instant). This in under a minute, an image could be created against which an OS level backup could safely be run. Once the backup was complete, the snapshot was unmounted and effectively destroyed.
