Borg backup: files found but no archive located

[BustedSec]

I am trying to migrate a nextcloud-aio instance from linode to local storage. I created a VM and installed nextcloud-aio, but I'm having an issue locating the borg backup files. The job runs fine and creates the borg folder, but within that folder there is no archive by the name that is given in the backup log. I tried rsyncing the entire folder over to the new machine and restoring from it, but it doesn't recognize it as a borg backup

The file structure is as follows:
config data hints.74 index.74 integrity.74 nonce README

here is the log:

By default repositories initialized with this version will produce security
errors if written to with an older version (up to and including Borg 1.0.8).

If you want to use these older versions, you can disable the check by running:
borg upgrade --disable-tam /mnt/borgbackup/borg

See https://borgbackup.readthedocs.io/en/stable/changes.html#pre-1-0-9-manifest-spoofing-vulnerability for details about the security implications.

IMPORTANT: you will need both KEY AND PASSPHRASE to access this repo!
If you used a repokey mode, the key is stored in the repo, but you should back it up separately.
Use "borg key export" to export the key, optionally in printable format.
Write down the passphrase. Store both at safe place(s).

Hi, on the new server with new AIO instance, did you instead of entering the domain, entered the backup location and backup password in the first step?

[BustedSec]

Yes

[szaimen]

I tried rsyncing the entire folder over to the new machine and restoring from it, but it doesn't recognize it as a borg backup

Can you send me the borgbackup container logs when it tries to restore the backup from this archive in the first step when you try to restore the instance from backup wothout entering a domain?

[szaimen]

Hi, can you check if /run/desktop/mnt/host/d/Nextcloud/Backups/backup works for you?

Hello, I just tried it and it produced the same "No 'borg' directory error. I initially tried it with exact capitalization and then switched to lowercase but to no avail.

I used the suggested path and added two dummy files to check if they are visible or not. The contents of my borg folder are as follows:

Mode                 LastWriteTime         Length Name
----                 -------------         ------ ----

-a----         9/27/2022   1:13 AM             73 README

and when ls is run from WSL2:
. .. README config data hints.1690 index.1690 integrity.1690 nonce

are these correct for the borg folder itself?

[BustedSec]

Apologies for lack of response. I ended up blowing away my instance and copying over the ncdata to a new instance then running a command to make it scan for that data. I no longer have access to the old one to post files

Same problem here after moving to a new server. Borg backup could unpack the archive just fine but nextcloud did not find an archive. Same log message with only ". and .." found.
