This is equivalent to -rlptgoD. It is a quick way of saying you want recursion and want to preserve almost everything.
-z –compress
With this option, rsync compresses the file data as it is sent to the destination machine, which reduces the amount of data being transmitted
-P
The -P option is equivalent to –partial –progress. Its purpose is to make it much easier to specify these two options for a long transfer that may be interrupted.
–delete
This tells rsync to delete extraneous files from the receiving side (ones that aren’t on the sending side)
–exclude
exclude files matching PATTERN
-b –backup-dir
With this option preexisting destination files are renamed with a ~ extension as each file is transferred. You can control where the backup file goes and what (if any) suffix gets appended using the –backup-dir and –suffix options.
But somehow it always created the Backup folder recursively again inside the Backup folder. So the first run created the /Backup folder, after the second run I’ve got /Backup/Backup, after the third run /Backup/Backup/Backup and so on..
The solution was to exclude the Backup directory using the --exclude command.
“If we are storing backups in the destination folder, or in a directory inside of the destination folder, the --delete parameter is going to delete old backups, as they are not in the source folder. Or attempt to as in the following situation:
Say, we already have a folder called backup inside of the destination directory, and we use rsync again, using --backup-dir=backup one more time. As rsync is going to attempt to delete every file and folder that is not in the source directory, it would backup the backup folder, which would create a backup folder inside our already existing backup folder, and then it would attempt to delete the backup folder and fail because it is using it to backup files.”
After a quick search I found this post. Seems like using mariadb:latest is not a good idea anymore. After switching to mariadb:10.5 and manually turning the maintenance mode off I could proceed the update process.
$ docker exec --user www-data nextcloud-app_1 php /var/www/html/occ maintenance:mode --off
Nextcloud or one of the apps require upgrade - only a limited number of commands are available
You may use your browser or the occ upgrade command to do the upgrade
Maintenance mode disabled
