Ok, explain to me...I took a 220MB system file and compressed it down to 28MB.
Obviously this is lossless as I can recover individual files from
within it that are things like extensions, fonts, etc.
I admit, JPEG, MPEG, etc. are lossful, but modems have been doing

Could we get an update from Dantz and Ecrix on the VXA/Retro Mac
issue, as reported by MacIntouch, 10-20-00 (see below)?
The post on MacIntouch goes a long way to explaining some of the
problems I've been seeing with my VXA drive. If not for having just
finishing rebuilding my LAN and upgradin
One (compound) word: Lossless
The compression methods that you are lusting after introduce errors
(artifacts) into the resulting decompressed data. This may be acceptable
for sound, photos and video but to totally unacceptable for storage of
system files, programs and most other data.

Hi there,
I'm looking for some help, ASAP.
A journalist from Smart Computing magazine would like to speak with a
Retrospect administrator backing up between 20 and 100 client systems with
our Windows version.
Please contact me directly if you are willing to speak with a member of the
press. [EM
Just a point of information:
JPEG compression schemes are called "lossy.". They achieve such high
compression ratios because they throw out a LOT of information that human
eyes don't care much about. Decompressing a JPEG will not (cannot) give you
back the original picture. The information in the
"Native" is the actual amount of data that the tape can theoretically store,
before compression. A 12.0 Gig file should fit on a 12.0 Gig capacity tape.
Suppose you are able to take a 16.0 Gig file and compress it down (using
PKZIP or whatever) to 12.0 Gigs. Now that 16.0 Gig file can fit on the
One word Matt: Compression
Native capacity is the amount of uncompressed data that will fit on the tape.
The drive has a hardware-based compressor that squeezes the data as it streams
from the SCSI port to the write mechanism.
The amount the data gets compressed depends upon the characteristi
One word: Compression.
Native capacities are with no compression. For example, your 12GB
drive can hold up to 12GB of un-compressed data. Normal hardware
compression can get up to 2:1 compression, giving a total maximum of
24GB.
Reality check, I've been getting about 27GB onto a 20GB/40GB
Hello,
I'm new to this list and subscribed because I have a question I hope one of
you will be able to answer for me.
I'm using Retrospect 4.2 for Mac, backing up a total of three Mac Servers to
an APS DAT drive. The tapes I use are Sony DDS3 125P which state a Native

Has anyone gotten Retrospect to see the MacOS running in OS X?
When the test the IP address from the Retrospect server, it 'sees' the
machine. However, when I try to connect to it directly for backups, it does
not see it.
Is there a workaround?
