Using duplicity to backup a folder on a certain event, how can I get a list of all available backup dates as I don't know in advance when the event occurred? I want to list the available dates as deja-dup does. Final goal is to restore a certain date from the list.

duplicity file:///backup-folder restore-folder --restore-time "yyyy-mm-dd"

I'm trying to backup a directory to a pre-existing Amazon S3 bucket using the following command:

duplicity --no-encryption system/ s3+http://MY_BUCKET_NAME/backup

However, I'm getting the following error consistently:

S3CreateError: S3CreateError: 409 Conflict
<?xml version="1.0" encoding="UTF-8"?>
<Error><Code>BucketAlreadyOwnedByYou</Code><Message>Your previous request to create the named bucket succeeded and you already own it.</Message><BucketName>vacationlabs</BucketName><RequestId>3C1B8C49469E3374</RequestId><HostId>4dU1TKf3Td6R0yvG9MaLKCYvQfwaCpdM8FUcv53aIOh0LeJ6wtVHHduPSTqjDwt0</HostId></Error>
  1. The S3 bucket is empty and does NOT have the backup directory
  2. The bucket is in Singapore region

Using Duplicity I can make an incremental, efficient backup to an untrusted remote storage. This works fine and I can restore files at a specific point in time (or the next backup after that).

Well now I want to know when in the history of all the backups did a specific file change. File change timestamp and size along with the backup timestamps would be sufficient.

Any way to do that with duplicity?

EDIT: I should clarify that I want to see every change/version to that file and not only the last, e.g. when it was first introduced, when it was change. That might be at multiple backup incremental backups.

I'm trying to work up a backup strategy for some clients, and am leaning towards duplicity for remote backup (already use rdiff-backup for internal/on location backups).

Is it reasonable to want a full backup every so often? Since duplicity increments forward, each incremental backup is relying on the previous increment, and all are relying heavily on the last full backup. Should that become corrupt, bad things happen. A related question: Does Duplicity test the incremental backups for consistency?

Assuming I do want a full backup every so often, how efficiently does duplicity create that full backup? Can/does it check file signatures and copy unchanged data from previous full backups/increments? Basically creating a new 'full' archive transferring new/changed data and merging existing unchanged data?

Right now my concern is that running a full backup is needed, but the consistent large bandwidth use of full backups will make this unreasonable for some clients.
