If file set contains large file backup fails with misleading error ".../tmp/pybackpack.iso: Operation not permitted".

[fusion]

Thank you for the software and this Ticket creation interface.

RELATED: Potentially Ticket #75.
SUMMARY: The error seem misleading to me. I think the file should have split the file or the user advised of the problem. The error given by the GUI gave me the impression that there was a problem with the user's creation privileges for file /tmp/pybackpack.iso.

Output of Pybackpack 0.5.6 GUI:
Backup failed; could not create CD image /tmp/pybackpack.iso: Operation not permitted

Output of Pybackpack 0.5.6 GUI Status Window:
Sun Nov 8 00:00:00 2009: Backup failed; could not create CD image /tmp/pybackpack.iso: Operation not permitted

Output of genisoimage (per Tickets 74 and 75):
$ genisoimage -v -r -o /tmp/pybackpack.iso /tmp/pybackpack.cdimage I: -input-charset not specified, using utf-8 (detected in locale settings)
genisoimage 1.1.9 (Linux)
Scanning /tmp/pybackpack.cdimage
File /tmp/pybackpack.cdimage/largefile.image is larger than 4GiB-1. -allow-limited-size was not specified. There is no way do represent this file size. Aborting.

"Do you really want to add "largefile.image" to the selection and use the third version of ISO9660 standard to support it?"
Select Proceed
