[Duplicity-talk] problem with restores from S3

[Russell Clemings]

I'm having trouble getting restores from S3 to work.

The problem is similar to this:
http://www.archivum.info/address@hidden/2008-08/msg00052.html
... but so far the tips there haven't helped.

Any suggestions appreciated, thanks in advance.


I'm using duplicity 0.5.02, boto-0.9d, Python-2.5.1, librsync-0.9.7,
GnuPG 1.2.6, GnuPGInterface-0.3.2. pexpect-2.1 on:
WHM 11.23.2 cPanel 11.23.6-S27698
CENTOS Enterprise 4.7 i686 on virtuozzo - WHM X v3.1.0


Backups seem fine (pardon the word-wrap on the command):
address@hidden s3backup]# cat backup.sh
#!/bin/sh
export AWS_ACCESS_KEY_ID=XXXXXXXXX
export AWS_SECRET_ACCESS_KEY=XXXXXXXXX
export PASSPHRASE=XXXXXXXXX
export GPG_KEY=XXXXXXXXX
SOURCE=/
DEST=s3+http://BUCKETNAME
/usr/local/bin/duplicity --tempdir=/s3backup --encrypt-key=${GPG_KEY}
--sign-key=${GPG_KEY} --include=/root --exclude=/** ${SOURCE} ${DEST}
export AWS_ACCESS_KEY_ID=
export AWS_SECRET_ACCESS_KEY=
export PASSPHRASE=
export GPG_KEY=

address@hidden s3backup]# ./backup.sh

I can see the resulting files in S3 (partial list using s3fox):
http://s3.amazonaws.com/BUCKETNAME/duplicity-new-signatures.2008-10-08T01:51:13-04:00.to.2008-10-08T21:58:33-04:00.sigtar.gpg

Now, here's the restore script:
address@hidden s3backup]# cat restore.sh
#!/bin/sh
export AWS_ACCESS_KEY_ID=XXXXXXXXX
export AWS_SECRET_ACCESS_KEY=XXXXXXXXX
export PASSPHRASE=XXXXXXXXX
export GPG_KEY=XXXXXXXXX
/usr/local/bin/duplicity -v9 --encrypt-key=${GPG_KEY}
--sign-key=${GPG_KEY} s3+http://BUCKETNAME/root /root1
export AWS_ACCESS_KEY_ID=
export AWS_SECRET_ACCESS_KEY=
export PASSPHRASE=
export GPG_KEY=

And the (unpleasant) results:
address@hidden s3backup]# ./restore.sh
