Nextcloud logs can be rotated, but it depends on your configuration. By default, Nextcloud does not automatically rotate its logs. However, you can set up log rotation using tools like logrotate on your server.

Here's how you can set up log rotation for nextcloud.log using logrotate:

Create a Logrotate Configuration File:

Create a file in the /etc/logrotate.d/ directory, for example, nextcloud:

edit /etc/logrotate.d/nextcloud as,

/var/www/nextcloud/data/nextcloud.log {
    su www-data www-data
    daily
    missingok
    rotate 14
    compress
    delaycompress
    notifempty
    create 640 www-data www-data
    sharedscripts
    postrotate
        /usr/bin/php /var/www/nextcloud/occ log:rotate --size=10M
    endscript
}

Explanation of the Configuration:
- /var/www/nextcloud/data/nextcloud.log: The path to your Nextcloud log file.
- daily: Rotate the log files daily.
- missingok: If the log file is missing, go on to the next one without issuing an error message.
- rotate 14: Keep 14 days' worth of backlogs.
- compress: Compress the rotated log files.
- delaycompress: Postpone compression of the previous log file to the next rotation cycle.
- notifempty: Do not rotate the log if it is empty.
- create 640 www-data www-data: Create new log files with specified permissions.
- sharedscripts: Run postrotate script only once, no matter how many logs are rotated.
- postrotate: Command to execute after rotating the log file.
- /usr/bin/php /var/www/nextcloud/occ log:rotate --size=10M: Rotate logs within Nextcloud itself to manage internal log rotation settings.

Reload Logrotate:

After creating the configuration file, reload logrotate to apply the changes:

suroot@hc4Bookworm:/var/www/nextcloud/data# /sbin/logrotate -f /etc/logrotate.d/nextcloud
error: skipping "/var/www/nextcloud/data/nextcloud.log" because parent directory has insecure permissions (It's world writable or writable by group which is not "root") Set "su" directive in config file to tell logrotate which user/group should be used for rotation.

/sbin/logrotate -f /etc/logrotate.d/nextcloud
error: /etc/logrotate.d/nextcloud:15 unexpected }
An unhandled exception has been thrown:
OCP\HintException: [0]: Memcache OC\Memcache\APCu not available for local cache (Is the matching PHP module installed and enabled?)
error: error running shared postrotate script for '/var/www/nextcloud/data/nextcloud.log '

sudo apt update
sudo apt install php-apcu
sudo phpenmod apcu
sudo systemctl restart apache2   # For Apache
sudo systemctl restart nginx     # For Nginx

/sbin/logrotate -f /etc/logrotate.d/nextcloud

By setting up log rotation with logrotate, you ensure that your Nextcloud logs do not grow indefinitely and are managed effectively. Make sure to adjust the file paths and permissions as per your server setup.
