2) Backups. I read another thread where the user indicated that they used UVBackup to create a file, and then the O/S backed up that file. Is that the general consensus? Others I have spoken with have indicated that they use only an O/S backup. In that case, what about locks and users on the system? Is there a best way to do backups?
I've only done OS level backups, so I can't objectively compare them to uvbackup, but this has worked fine for us since migrating to UV in '96. We do frequent restores of various archived files for accounting report requests. Fortunately we're a 9-5 operation, so I have a window at the end of the day where I can be sure no updates are happening on the filesystem.
If you can't prevent writes during your backup, and you don't have a mirrored filesystem you can break apart, there are a number of backup solutions that can handle open files. St. Bernard and Unitrends Backup Professional are a couple. St. Bernard works in conjunction with the backup software of your choice, and Backup Professional has built-in open file management. It's my understanding that all files are saved in a consistent state by monitoring the filesystem at the OS level and caching any disk writes until the particular file is backed up. This gives you a backup of your filesystem as it was at a specific point in time. Of course you still have to start your backup at a point in time when no transactions are in mid-stream if you want to be able to restore everyting to a consistent state.
