[BUG] 0 snapshots and 0 revisions after backup

Support
#1

Hello,

I’m having a strange problem with Duplicacy and S3.
I just set up a backup via the web user interface and everything went well.

Except that Duplicacy can’t find any backups on the S3 bucket and tells me in the logs:

Running check command from /cache/localhost/all
Options: [-log check -storage OVH-S3 -a -a -tabular]
2026-01-19 16:01:17.215 INFO STORAGE_SET Storage set to s3://rbx@s3.rbx.io.cloud.ovh.net/backup/./

2026-01-19 16:01:17.809 INFO SNAPSHOT_CHECK

As we can see, the backup seems fine and i can see the 2TB of data on my S3.

I have another backup task to an SFTP that works fine.

How can I resolve the issue, given that I have already restarted the check several times and nothing has changed?

Hi all,

I made the backup to OVH S3 using this path:

s3://rbx@s3.rbx.io.cloud.ovh.net/backup/./

Could the ./ at the end of the path be preventing Duplicacy from recognizing the snapshots?

I have the same thing via SFTP, but the problem does not occur. Could this be related only to S3?

The problem comes from the ./ which is not correctly supported. I just moved the data to a folder so that the path is in the form: s3://rbx@s3.rbx.io.cloud.ovh.net/backup/nas/ and it works, it just found the snapshots :slightly_smiling_face: .
