Info: You can run a backup/restore while sending and writing data to the same buckets. The data will not replaced from restore.


Backup

#Change user
sudo su - influxdb
 
#Export environment variables
export INFLUX_TOKEN=<INFLUXDB_ADMIN_TOKEN>
export INFLUX_CONFIGS_PATH=~/profile
export TIME=$(date + "%Y%m%d%H%M%S")
export BKR_DEST=/var/lib/influxdb/backup
 
#Check InfluxDB connection
influx config ls
 
#Start Backup
influx backup $BKR_DEST/bkr_full_$TIME


Compress & move Backup

#Compress
tar -cf bkr_full_$TIME.tar bkr_full_$TIME
 
#Copy the Backupfile to destination
rsync -aP /var/lib/influxdb/backup/bkr_full_$TIME.tar <YOUR_USERNAME>@<DESTINATION_HOST>:/<DESTINATION_PATH>


Restore

Prepare archive for restore

#Change user to root
sudo su -
 
#Change owner of the Backupfile
cd /<DESTINATION_PATH>
chown -R influxdb:influxdb bkr_full_<TIMESTAMP>.tar
 
#Change user
sudo su - influxdb
 
#Unpack the archive
tar -xf bkr_full_<TIMESTAMP>.tar

Restore the Backup

#Export environment variables
export INFLUX_CONFIGS_PATH=<PATH_TO_THE_CONFIG>
export INFLUX_TOKEN=<INFLUXDB_ADMIN_TOKEN>
 
#Check InfluxDB connection
influx config ls
 
#Start restore
influx restore --full <PATH_TO_BACKUPFILE>/bkr_full_<TIMESTAMP>
 
#Check if restore is running with htop
htop

Restore hangs

If there restore hangs restart the InfluxDB service: 

#Restart InfluxDB service
systemctl restart influxdb.service
 
#Check status
systemctl status influxdb.service
