This will depend on various factors:
- the amount of data you want to sync
- the speed of your internet service provider
- the load on our vaults
- the type of data you are trying to sync (i.e. small notepad files or large image files)
Keep in mind to not put too much data (too many files) on your Vault at once, it's always better to upload it in smaller parts. That way it's also easier / faster to take out any possible conflicts.
