Hi Terry, > Can anyone explain hot backup mode in the context of file server as > opposed to a database? Can it be done?
You mean you'd like to snapshot a filesystem so its own internal data is in a consitent state for backing up? Although the files' data might be partially complete, e.g. tar creating a large tar file might only be half done. Sure, they're call snapshots, typically, and normally employ copy-on-write so the snapshot is quick to produce and takes little extra storage; only writes modifying the data in the snapshot take extra space until the snapshot is deleted. Obviously, you still have to ensure important files, e.g. database ones, are internally consistent when the snapshot takes place, but since the snapshot is quick this doesn't have such an impact.
