[BUG] Mirror repo not finding snapshots to sync

[hbilbo]

Prerequisites

• I have read the troubleshooting guide

Rclone Pre-flight Checklist (if applicable)

• This issue is NOT related to rclone (skip if not using rclone)
• I have tested rclone listremotes and rclone lsd remote: on the host and they work
• I have verified the rclone config is mounted into the container
• I have restarted the container after config changes

Bug Description

I have created a backup job and successfully backed up data to a B2 bucket using the S3 repo option. After backing up 3 times (3 snapshots) I tried to create a mirror to an icloud remote configured using rclone, however whenever I hit "sync more snapshots" it doesn't seem to find my 3 existing snapshots in order to back them up to the mirror.

You can see in the photo here my existing snapshots are there, but zerobyte doesn't find them in order for me to back them up. It just says "Sync 0 snapshots" with the option still greyed out since none are loaded.

Steps to Reproduce

1. Create a backup job to a B2 bucket and run a couple of backups.
2. Configure an icloud remote using rclone and add the rclone config to the zerobyte container
3. Configure an icloud repo in zerobyte using the existing rclone config
4. Verify the repo populates in icloud
5. Attempt to add the icloud repo as a backup mirror and sync existing snapshots

Expected Behavior

Hitting the "sync more snapshots" should find existing snapshots for backing up to the icloud mirror remote.

Zerobyte version / commit

Deployment Method

Backup/Repository Context

Initial backup is to a B2 bucket using the S3 repo option. Mirror repo is setup to an icloud rclone remote

Thanks for reporting, I think it may be due to how slowly your repository is answering with the list of snapshots and we reach a timeout internally that is not surfaced in the UI. I'll work on a fix

I think you could be right, I also noticed that behavior with onedrive when attempting to sync snapshots for the first time it didn't show any available to sync. But then trying it again resulted in them showing up after a few seconds, which seems like some kind of timeout issue.
