Re: File Backups

[Subject Prev][Subject Next][Thread Prev][Thread Next]
I believe the program Bill is refering to is Stacker.  Microsoft was sued by
the company that makes Stacker and the current version of Drivespace that
comes with MS Plus is, infact, the Stacker technology. I tend to disagree
with Bill, however, I never filled my drive completely - especially since
Windows acts unpredicably when there is less than 10% of your drive left for
a swap file. I ruined an older drive because of this problem, not a
compression problem.
I have been using Drivespace for over three years and have used Stacker
before that. Granted, the original version of Stacker was a bit
unpredictable, but I have found Drivespace to be extremly stable. In fact, I
compress my Zip drives to obtain approximately 180 megs per disk. You need
to have Drivespace installed and mount the drive, but it is a great way to
keep your projects on the same disk.
One warning, the previous version of compression called Doublespace from
Microsoft was unstable and could, if you are using it, corrupt data.
In anycase, whether or not you use a compression program, you need to make
backups of your data at the very least. From one who has learned the hard
way - you can take that advise to the bank.
