Re: File Backups

[Subject Prev][Subject Next][Thread Prev][Thread Next]
While I'm not as sharp about OS's as Dennis is, I would still be concerned
about Drivespace. You never get something for nothing. I also wouldn't think
that the Windows swap file issue matters since the swap file does not reside
on the compressed drive. The problem is that, when you try to copy a file
either a "normal" floppy or Zip disk and there is no room, you get a simple
is full" message. This is not the case with a mounted drive (at least when I
did it
on an old version of Stacker). The thing crashed and I was up until 5:00 am
to recover data. Even MS tech. support has told me that a drive set up for
space is not as reliable as a standard drive. For those of you more
than me, go ahead. Otherwise, buy more Zip disks.
