I was planning to create a server cluster for two NextCloud servers, and I found this answer in the forum, the question is that, in the third step of the answer
Use DRBD to sync all Nextcloud folders (installation and data)
I’m using Amazon S3 as a primary storage account, does that also needs syncing? since I intend to use the same S3 bucket as the primary storage for both NextCloud servers, also what is meant by (installation and data) ?
another question, does this solution, or syncing two NextCloud servers in general require any changes to the file
config.php ? better to know before messing up the servers
