`--vfs-cache-poll-interval`. Secondly because open files cannot be
evicted from the cache.
You **should not** run two copies of rclone using the same VFS cache
with the same or overlapping remotes if using `--vfs-cache-mode > off`.
This can potentially cause data corruption if you do. You can work
around this by giving each rclone its own cache hierarchy with
`--cache-dir`. You don't need to worry about this if the remotes in
use don't overlap.
### --vfs-cache-mode off
In this mode (the default) the cache will read directly from the remote and write

on the operating system where rclone runs: "true" on Windows and macOS, "false"
otherwise. If the flag is provided without a value, then it is "true".
## Alternate report of used bytes
Some backends, most notably S3, do not report the amount of bytes used.
If you need this information to be available when running `df` on the
filesystem, then pass the flag `--vfs-used-is-size` to rclone.
With this flag set, instead of relying on the backend to report this
information, rclone will scan the whole remote similar to `rclone size`
and compute the total used space itself.
_WARNING._ Contrary to `rclone size`, this flag ignores filters so that the
result is accurate. However, this is very inefficient and may cost lots of API
calls resulting in extra charges. Use it as a last resort and only with caching.
