I'm backing up files to a remote webdav share. I'm using rsync so that it's at least incremental. However it's not going very fast at all, and so I'm wondering if I've configured it correctly.

Will the following command do an incremental backup if run multiple times?

```
# Backup
sudo rsync -av --delete --progress \
--exclude '*@SynoResource' --exclude '@eaDir' \
--exclude '.TemporaryItems' \
--exclude '*.vsmeta' --exclude '.DS_Store' \
/mnt/configs/ /mnt/remote/configs

```

If it does, how can I then speed it up otherwise?
