OverflowError while writing signatures

[Compizfox]

Hi,

This is my first time backing up with Duplicity. I'm trying to backup around 450 GB total. The command I use is:

duplicity --volsize 1000 --asynchronous-upload --full-if-older-than 1M --encrypt-key "$keyid" --exclude-filelist "$excludelist" "$local" "$remote"

My first full backup is almost finished, but on the end I get this error:

Writing duplicity-full-signatures.20160315T174511Z.sigtar.gpg
WebDAV PUT /remote.php/webdav/duplicity_ILOS/duplicity-full-signatures.20160315T174511Z.sigtar.gpg request with headers: {'Connection': 'keep-alive', 'Authorization': 'Basic '}
WebDAV data length: 3944337508
Attempt 1 failed. OverflowError: string longer than 2147483647 bytes

Because of this, it can't finish the backup. What should I do?

Duplicity version 0.7.06
Python version 2.7.11
FreeBSD 10.2-RELEASE

Thanks in advance.

This is a known problem with large backups, the sigtar file gets to be
larger than 2GB. To work around this you will need to use the option "
*--max-blocksize=20480*" to increase the blocksize of the signature. This
should get you below 2GB.
