Nixpkgs: snapper: Doesn't take snapshots

Created on 4 Feb 2018  路  4Comments  路  Source: NixOS/nixpkgs

Issue description

I'm using snapper on btrfs and it doesn't seem to take automatic snapshots, even though the services seem to be running and the timer is working. I'm not sure what other info I can give you.

It does, however, take snapshots manually.

Steps to reproduce

Install snapper, add configuration to whatever.nix.

Try adding the following to your config: 

services.snapper.configs.root.extraConfig = ''
  TIMELINE_CREATE="yes"
'';

According to the man page (snapper-configs) the default is no for time line snapshots.

Can you post your config (the part with the snapper config)?

services.snapper.configs."root".subvolume = "/";
