There is no hard limit to the number or size of files Snap Backup can handle.
That
being said, Snap Backup has not been rigorously tested on large file sets. My
guess
is that the number of files is probably not an issue (I've done backups with
lots of
smaller files). The issue is probably with the overall size of the resulting
backup
file. I believe the zip format originally did not support files larger than
2GB. I
think the limit is now 4GB, but it should be extended soon.

Workaround:
Use the profiles feature (File --> Multiple Profiles --> On) in Snap Backup to
define
multiple backups enabling you to break your zip file into two or three smaller
zip files.

What are the size limitations to the backup files? I've tried saving Outlook
PST files, (2GB), and also larger
database files (20GB). The database files always complete with a small
fraction of the size (20 > 3GB) but when I
try to open the ZIP file to confirm the data, it opens empty.

A warning message is now displayed if the zip file is larger than 3.8 MB (allow
for 0.2 MB margin of error).
The new Zip64 format gets around the 4 GB limitation. Java 7 (release date
early 2010?) is slated to support
Zip64.
