<![CDATA[Backup error 'copy exited with code 1 signal null']]>Hi guys

In the last two days I am getting the following 'Failed to backup' email with the following text:

Cloudron failed to create a complete backup. Please see https://docs.cloudron.io/troubleshooting/#backups for troubleshooting.

Checking the backup system, I verify that the backup has been generated in all the applications, but in the Cloudron backups section the error 'copy exited with code 1 signal null' appears.

Reviewing the log, these are the last lines that show where the failure occurs:

Apparently, the failure occurs when the Cloudron itself is backed up, since as I said before, the copies of all the applications are made.

Any hints or suggestions to solve the problem?

Thanks.

--delete-before          When synchronizing, delete files on destination before transferring

I will change the mount command within the crontab and launch a new test to see if it is corrected that way.

Thanks for the help @nebulon 👍

If you do not need to back up this file then you can edit the backup plan removing that file from your backup.

Is there by any chance some way to mount the drive with some sync flag? Might reduce overall speed but maybe is more solid. I don't have any experience with rclone mounts from google drive though.

I have rebooted the server, removed several heavy applications from the backup (to rule out memory issues) and the only LAMP application containing non-Cloudron code.

The result of the new backup is the same, the error occurs when saving the file /mnt/backups/snapshot/box.tar.gz

Is this file the only one to be replaced? Is that so?

Could it be that when it is replaced (and a new one is not generated like the rest of the application files) it may give an error due to the time lag in the synchronization with Google Drive through rClone?

What I do not know is why this error has started to occur for two days, when the copy system has worked well in the previous days ...

The folder has a Google Drive team drive mounted with rClone to store the backups.

It has been working normally from the beginning except for the last two days, which is when it has started to give this error.

Cloudron is already updated to version 6.2.4

What is failing looks like a regular file copy, so the I/O error indicates a filesystem problem here. Maybe try to remount this?
