ZipFile greater than 4GB?

[WDPeterson]

I'm getting a warning that the zip file is greater than 4GB and therefore may be corrupt. Is the product based on the old open source zip code, which was limited to 4GB? If not, shouldn't it be able to zip up more than 4GB?

Older versions of Zip had a 4GB limit, and so older versions of Java shipped with a Zip library that also had a 4GB limit. Snap Backup is a Java application, so it was saddled with the same limit.

With newer versions of Java, that limit should not apply. However, you should definitely test the backup file to make sure it works properly.

Marking this issue as an enhancement since the 4GB limit needs to be researched and tested, and the warning message should be removed if the limit is not longer applicable.
