I understand that the physical file can't exceed 2GB (at least prior
to OS9), but I don't understand why this is a barrier to doing a file
backup set that exceeds 2GB in total. Other programs are able create
segmented files when they reach a given size. If I'm reading the
message that Eric posted to the list a few months back (see below)
correctly, even your own program understands how to do segmentation
when dealing with removable media. So my question is, why can't it do
segmentation (via containers or whatever) when dealing with a file
backup set on a fixed drive that exceeds the 2GB mark?
Barring some technical reason, maybe that option can be added to the
next update (ideally where the user can set the segmentation size)?
This has benefit of working even for those of us that choose not to
upgrade to OS9. It also provides a mechanism for dealing with the
issue when we start to reach OS9's file size limits. Although at 2TB
hopefully we wont reach that point for a year or two. :)
Thanks
