Comment 25 for bug 385495

I have finally determined that this is what is causing my backups to error out. My sigtar file is reaching 1.8G and 1.9G on an NTFS USB drive. Presumably when it hits 2G it throws an error ("Error splicing file: Input/output error" pops up), though I have not been able to find a log file that tells me any details about this error to confirm my suspicion. It looks like this has not been addressed in some time.

This is a deal-breaker for me. I cannot use the duplicity/deja-dup solution in Ubuntu or recommend that others use it until this issue is resolved. Using backup with a preformatted (and therefor NTFS) external USB drive is a fairly common use case, and 2GB files should be avoided (or broken up on detecting this error or, at least, the option to avoid them should be included).
