Well, for starters, you can’t have files in a partition that are >2G,
I think the limit for a file is actually 2G - 1 or something. That aside,
as igor mentions, you CAN backup to a raw partition, which is also why
the whole DVD-RAM thing works (right igor?).
You’re right about the limit, it is 2Gb. As of backup, if one wants to
backup to a filesystem it is usually because one wants to backup
individual files, rather than large consolidated tar archives (otherwise one
would rather use raw device because it is faster, especially in the case of
DVD-RAM). That makes the issues somewhat less important and ‘DVD-RAM thing
However it does limit options. When single size of DVD-RAM could hold
maximum 2.6Gb, it was almost moot point, but now they can hold twice that
much and gonna double their capacity yet again in short term future.
This could be a real gotchas when people start housing big projects
on self-hosted RTP considering backup…
In all honesty, this isn’t specific to QNX. Linux ALSO has a 2G file limit
within their filesystems. The difference, of course is that linux
tapes, and qnx6 does not.
NTFS supports much larger files (i don’t even know how large, but they can
be larger than 4Gb). FAT32 supports files up to 4Gb. I don’t see why QNX
could not, especially since they are about to change filesystem to support
