Forced Compression in Retrospect 7.x (DVD-RAM)


Recommended Posts

To any in the know:


I installed Retrospect 7.0 purchased at local store on my Dad's Win2K machine to automate his backups...after a few of the updates/patches downloaded I seem to be able setup for automated backups to DVD-RAM (4.7GB, Double Sided = 9GB).


It will prompt my Dad to put in the particular DVD, but for some reason I cannot get the Compression to work at all. I know that I have set it on and did some test with "other" brand backup and zip and I should be getting like 40% on the files I am backing up. [mostly documents]


Does anyone know how to Force Retrospect 7.x either by registry, script or other to try and Compress everything. It treats the DVD-RAM as if they are Hard Drives, but that still makes no sense why it refuses to enable compression when I select it.


I would like both the short-term workaround that might force Retrospect 7.x to try and compress everything and the long-term fix where that Toggle has meaning!


Even if it was an 80GB external drive why should Dantz disable compression?!?


Any ideas?

Thanks Nate, but I am telling you it is doing the Math wrong. Based on the access speed of my DVD-RAM (which looks like a hard drive) vs. even some minor compression would speed up the backups and save me DVD space.


MS$ has a lot of crap that is smarter than its own good like that LSASS backdoor that has been heavily exploited.


I work in R&D and run 2 Databases at work...at least for DVD-RAM backup it is doing zero compression independent of if I am backing up a bunch of txt files mixed with exe files.


My guess is it is checking a few of the files and then giving up on compression.

Retrospect bases its compression on file type for each file. It never "gives up" Files that Retrospect thinks are already compressed will not be compressed in backup. I believe EXE files are excluded from compression.


What happens when you run a test backup with just text files?
