Re: Large Backups now a breeze in OSX

For some time now Mac OS8.x-> 9.x users have not been able to use

This information was hard to find on the Retrospect Backup, Dantz.com website.

There is a 2gig file size limit and HFS, HFS+ is the season. But now
thanks to Unix that door have been flung open.

FYI... HFS+ does not have a 2gig file limit only HFS. HFS+ supports file sizes of 2^63 (see <http://developer.apple.com/technotes/tn/tn1150.html>).

The older Mac OS APIs have a limitation but new APIs got added when HFS+ came into existence circa Mac OS 8.1. If software stuck with using the older APIs then they are still limited (not until Mac OS 9 did the finder support copying files greater then 2GBs in size).

So you can use UFS or HFS+ under Mac OS X as long as your software is written to utilize the newer APIs. If they use the older APIs then using UFS will not make a difference.

Also HFS+ is generally the better choice is you are using Mac OS X.

All you do now is format your
for drive's partition for Unix (not HFS) then load OSX and Retrospect 5
for Workgroups MacOSX.

So you can use HFS+ or UFS and Retrospect 5.0.
