It definitely won't be subject to the same errors. VaultPress can connect to your site via SSH, which is the preferred method for it to directly access both the files and the database, or via SFTP/FTP for the files and MySQL for the database.

VaultPress uses one of the above methods to directly access your files and database, determine the changes (often sent via a ping, like a post being published or updated), and then transfer only the changed data to its servers.

All processing and storage is then done as describe in the announcement linked to in the article above. Because the processing is done on VaultPress's servers, and your server only need to worry about transferring the changed data only, it should never timeout, and it really shouldn't conflict with anything else either.

They recently launched a 5-day free trial, as mentioned above, so there's no reason not to try it. :)
