Sorry to hear you’re facing problems 
Nextcloud version : 12
Operating system and version: Ubuntu 16.04
Apache
PHP version: 7
Hi there, my data folder is configured as S3:
config sample:
‘objectstore’ => array(
‘class’ => ‘OC\Files\ObjectStore\S3’,
‘arguments’ => array(
‘bucket’ => ‘nextcloud’,
‘autocreate’ => true,…
So I can’t really use rsync etc for backups.
I need to backup for DR and for getting specific files back due to mistakes.
Any idea?
