Nextcloud documentation

Nextcloud recommends a 5 Minute interval:

value =5m in minutes

sudo snap set nextcloud nextcloud.cron-interval=5m

sudo snap restart nextcloud.nextcloud-cron

sudo nextcloud.occ background:cron

sudo snap set nextcloud nextcloud.cron-interval=-1

value =5m in minutes

sudo snap set nextcloud nextcloud.cron-interval=5m

By default the cronjob interval up until Nextcloud 29.0.x was 15 minutes. Nextcloud from 30.0.x recommends a 5 Minute interval:

To adjust it (to 5 minutes) simply run:

$ sudo snap set nextcloud nextcloud.cron-interval=5m

If you want to disable the cronjob completely, run:

$ sudo snap set nextcloud nextcloud.cron-interval=-1

To reenable it again simply set the nextcloud.cron-interval snap variable to a value that isn't -1
