Frequently Asked Questions

How much data can I sync from my NAS to Google Drive for free?

With a free Google account, you get 15GB of storage shared across Google Drive, Gmail, and Google Photos. If you need more space, you'll need to upgrade to a paid Google One plan. However, you can be selective about what you sync to stay within the free limit.

Will syncing to Google Drive slow down my NAS?

During active sync operations, your NAS will use some CPU, memory, and network resources. The impact depends on your NAS specs and the amount of data being synced. To minimize performance issues, schedule syncs during off-hours and limit the bandwidth used for syncing during busy periods.

Can I sync multiple NAS devices to the same Google Drive account?

Yes, you can sync multiple NAS devices to a single Google Drive account. Just make sure to use different destination folders for each NAS to avoid conflicts. Keep in mind that all synced data will count toward your single storage quota.

How secure is my NAS data when synced to Google Drive?

Google Drive provides good security with data encryption in transit and at rest. For extra security, several of the methods discussed (Rclone, Restic, Synology Cloud Sync) offer client-side encryption options, which encrypt your data before it leaves your NAS. This ensures that even Google can't access your unencrypted files.

What happens if I delete a file on my NAS - will it also be deleted from Google Drive?

It depends on your sync settings. With one-way sync (backup mode), deleting files on your NAS typically won't delete them from Google Drive, preserving your backup. With two-way sync, deletions usually propagate to both sides. Most sync tools let you configure this behavior, so check your specific tool's settings to ensure it behaves as expected.
