when I backup Influxdb on my Ubuntu 16.04 LTS on Lab, it uses v0.10.0,

sudo service influxdb stop
sudo tar cvf influxdb.backup.2017.04.07.tar  /var/lib/influxdb/data /var/lib/influxdb/meta  /etc/influxdb/influxdb.conf
sudo service influxdb start

I try to restore the backup file into my personal System76 laptop which has InfluxDB v1.2.2. It failed with error in /etc/influxdb/influxdb.conf

1

sudo tar xvf influxdb.backup.2017.04.07.tar  -C /

So, I delete the /etc/influxdb/influxdb.conf and then try to install InfluxDB by the command,

1

sudo apt-get install influxdb

Try to start the InfluxDB service by $influxd It says “/etc/influxdb/influxdb.conf” not found.

So, I have to download the official version config.sample.toml and copy it to /etc/influxdb/ folder, then rename it to influxdb.conf

Finally, it works.

sudo service influxdb start
