There are currently three levels: - - `none` (default): Does not do any syncing when writing chunks. This is fast + - `none` : Does not do any syncing when writing chunks. This is fast and normally ok, since the kernel eventually flushes writes onto the disk. The kernel sysctls `dirty_expire_centisecs` and `dirty_writeback_centisecs` are used to tune that behaviour, while the default is to flush old data after ~30s. - - `filesystem` : This triggers a ``syncfs(2)`` after a backup, but before + - `filesystem` (default): This triggers a ``syncfs(2)`` after a backup, but before the task returns `OK`.
