Backup Errors

[pdrupp]

Hi, i have recently setup a 2nd Cloudron instance on Netcup that i only use as a mail server. Currently around 50 Mailboxes with a total of 180GB of data. I do hourly Backups to our on-prem Synology via Tailscale that work fine and fast. Usually between 1 and 5 minutes. Once per night i still want to make a direct backup from Cloudron to Wasabi S3. I already found out that rsync takes a lot of time, so i switched to tar for a few days, and that worked great, but still i would prefer rsync. There's pros and cons for both settings. So i switched back to rsync and the backups work, but during the upload i see a lot of 500 errors.

Here's an example:
Retrying (1) copy of 6sRz+6WKso8LhqISaUkfxZZhA02YwUGbjJPLNwP5YGg/viNdvgKqX2Z0h2Q8PWusD+r432QXN4DIGBmVbmWqqCQ/9EOUhxrSmnxrOk0C1mGNy73UPTrETurLwHZIMWcTaW4/WLjr6ukIaB+olQVkGmjQamtztBwQ0qCzvHqrSTsGUEJWr5EBiWSvHYqYxTOw-O7i/aBD30AGnxxwdei3sZYSXWzbyX2wX7ZCpUkgkj5czFDc/OL8uir0yWaEDftripDEB6aTiwnfGsOK+DCpt3UstR3LUPK4Lq3Vi6Y5W-I4dG6PXKSZaCtohB-DL-mGfDablPYtq-JDXCc3ke9wPI0otcFI. Error: InternalError: We encountered an internal error. Please retry the operation again later. 500

What is this error, how can i fix it and how come the backup still finishes in a positive state?

The error message itself is coming from the service that you are backing up to. Since you mentioned synology, does it have some s3 logs?

Hey joseph, thx for your reply. No this error is when backing up using Cloudrons Backup Module to Wasabi S3. The Synology makes a complete VM Backup in the background, no errors there. I hadn't activated logging in S3, i will change that and run a new backup.

I'm thinking about the possibility that the length of the encrypted filenames might be too much for Wasabi... I'll dig deeper...
