Minimum memory required

restic can be memory hungry. I’m running a few servers with no swap and I managed to kill some of them during a backup.

For that matter I’ve introduced a parameter in the global section called min-memory. The default value is 100MB. You can disable it by using a value of 0.

It compares against (total - used) which is probably the best way to know how much memory is available (that is including the memory used for disk buffers/cache).
