Reverting a contacts database

Last synced 2 weeks ago by Frans Leys

It is not possible to revert a sync executed by PieSync, yet certain apps take constant snapshots of the contact database, so even if you forgot to take a backup of your data, you can still go back in time and restore the database you had.

ONLY FOLLOW THE INSTRUCTIONS BELOW IF YOUR SYNCS ARE TURNED OFF

Google Contacts

  1. Turn off your active syncs - and remove the connection all together if you plan on setting up this connection again.
  2. Go to Google Contacts, log into the right account, and hit More > Undo Changes on the left and choose to go back to an earlier point in time, nearest to setting up the sync.

Apple iCloud

  1. Turn off your active syncs - and remove the connection all together if you plan on setting up this connection again.
  2. Go to your iCloud settings and choose to restore contacts at the bottom of this page.

Contacts+

  1. Turn off your active syncs - and remove the connection all together if you plan on setting up this connection again.
  2. Go to your settings and restore a backup.

Other apps - delete contacts added through the sync

  1. Turn off your active syncs - and remove the connection all together if you plan on setting up this connection again.
  2. While not available in all apps - you should be able to run a query identifying contacts created through PieSync. Set up a filter through a timestamp approximating when you turned on the sync and delete the contacts.

    The following example is from Pipedrive CRM, for a sync that was executed on 2nd September. A similar approach should be available for other CRM's too.

Note - this method is not fail proof. A query on "create time" will of course also identify false positives - contacts that were added but not by PieSync. Some CRM's allow you to filter on Source instead of timestamp, which is more accurate. Example - FollowUpBoss

Unfortunately, neither method will identify contacts that already existed in your CRM, yet were modified by the sync.
