What is Two-Way Sync?

Two-way synchronization (or bi-directional sync) is all about mirroring data between two business tools. This means that all newly created records in one application should be immediately (or almost immediately) created in the other application, and all updates to existing records should be reflected in the other application's records.

Ideal two-way sync to map common fields in a way that ensures the maximum amount of data is synced and avoids any circular updates or creation of duplicate records between tools. At present, there are two most common sync methods, namely:

  • Data polling. A data source (such as the Google Calendar Meeting API) is periodically polled for any updates. These updates typically describe records that were created or updated since the last sync. In some cases, you can also get a list of deleted records, so you can sync deletions as well.
  • Web-hooks. It's very similar to the previous type, but you don't check for updates at regular intervals. Instead, you'll be notified of the newly updated app and then perform a sync. This is a more efficient way of syncing, but unfortunately, not many tools support web-hooks.

  • Consistency: Keeps your local device and cloud storage updated with the same photos, ensuring you have access to all your images across platforms.

2. Google Photos Cloud Sync

Although multiple accounts can gain more storage space and are easier to manage, using multiple accounts to store data will also make it difficult to find and obtain data. In this case, the user can sync the data of two or more accounts in real-time. In this way, when the data in one of the accounts cannot be obtained, the user can obtain all the data from the other account, which is very convenient.

MultCloud is the easiest tool to sync 2 Google Photos and other cloud accounts. Currently, MultCloud supports more than 30 mainstream cloud drives, including Dropbox, Dropbox Business, Google Drive, Google Workspace, Google Photos, OneDrive, OneDrive for Business, MEGA, iCloud Photos, Box, pCloud, Amazon S3, and even NAS, WebDAV, FTP/ SFTP, Shared with me and Shared Drive, so you can manage multiple cloud storage accounts in one place.

To perform quick Google Photos sync between accounts without downloading or uploading, you need to use MultCloud's Cloud Sync feature.

✔️Automatic Sync: The system automatically enables the sync task after setting the time.
✔️Fast Sync: The system can update changed content in real-time.
✔️Custom Sync: Multiple sync modes are available, including two-way sync.
