The intended usage here is to basically kick restic as a background "do it, but don't bother my normal load" process. This allows passing the following environment variables in to influence scheduling: - NICE: usual CPU nice. Defaults to 0. This requires CAP_SYS_NICE to set a negative nice (IE, prioritize). - IONICE_CLASS: usual ionice class. Note that setting realtime requires CAP_SYS_ADMIN. Also note the actual ionice default is "none". - IONICE_PRIORITY: set the priority within the given class. Ignored if no class is specified due to class default of "no scheduler". --------- Signed-off-by: Brian Harring <ferringb@gmail.com> Co-authored-by: Michael Eischer <michael.eischer@fau.de>
