[Cialug] USB mounted drives

[Don Ellis]

One of our client systems has a backup script installed that does something
like this. When I went to their shop Monday I noticed that when the backup
script runs, it starts with mounting the USB external drive, runs the
backup, then unmounts the drive. Running under Linux, backing up a directory
that was shared with a Windows VM. I think this discussion tells me why it's
done this way; I had not tried things like this myself over a period of
time. External drive cases are usually attached/detached manually, so it's
not an issue. Leaving one attached, I'll watch for this next time I get a
chance.
