I just noticed that a VM wasn’t backed up by my restic cronjobs the last days. I did a “restic snapshots” and got the follwoing error
Fatal: unable to open config file: Stat: The difference between the request time and the current time is too large. Is there a repository at the following location?
I noticed that the system time of the machine was about 30 minutes late. I will check later why exactly this was the case. I just wanted to leave this warning here - incorrect system time can lead to automated backups not beeing done - at least with S3 backend.
