The command charm backup-keys
is used to create a backup of the Charm encryption keys required for a Charm application. This command ensures that the encryption keys are safely stored in case they are needed for recovery or restoration purposes.
The -o
option is used to specify the output file where the backup of the keys will be saved. In this case, ${path-to-output_file-tar}
is a placeholder for the desired path and name of the output file in the tar format. You need to replace ${path-to-output_file-tar}
with the actual path and filename where you want to save the backup file. For example, you can replace it with /home/user/charm-keys.tar
to save the backup as charm-keys.tar
in the /home/user
directory.
So, when you run the command charm backup-keys -o ${path-to-output_file-tar}
, it will create a tar file at the specified location containing a backup of the Charm encryption keys.
