What is the data backup and recovery mechanism of the Prometheus system like?
The data backup and recovery mechanism of the Prometheus system can be performed in the following ways:
- Data Backup: The data of the Prometheus system is stored in a local time series database, and can be backed up by regularly copying the Prometheus data directory (default is /data). Tools like tar, rsync, etc. can be used to back up the data directory to remote or cloud storage, in order to prevent data loss.
- Data recovery: If data is lost due to accidental deletion or damage, data recovery can be done by restoring from a backup. First, stop the running Prometheus instance, then unzip or copy the backup data directory into the original data directory, and finally restart the Prometheus instance to restore the data.
It is worth noting that the Prometheus system does not offer an official data backup and restore tool, so users will need to implement the process on their own. It is also recommended to regularly backup data to ensure its security and reliability.
