I have installed canvas with the help of bitnami VM.
When I am trying to take the backup, it is throwing message as mentioned below.
bitnami@debian:~$ sudo tar -pczvf application-backup.tar.gz /opt/bitnamitar: Removing leading `/' from member names/opt/bitnami
How to resolve?
I cannot reproduce your problem, any case you can solve that by using the options -P, --absolute-names in our command, i.e.:
sudo tar -pczvf -absolute-names application-backup.tar.gz /opt/bitnami
Hope it helps.
