Create a bookmark in Data Control Tower

A bookmark marks a specific snapshot in the dSource timeline and prevents it from being automatically removed by the retention policy. You can also use bookmarks as provision points when creating VDBs.

Long-lasting bookmarks can significantly increase storage usage. All snapshots that depend on a bookmark are retained, regardless of the configured snapshot policy.

Steps

1. On the Timeline tab, locate the snapshot that you want to bookmark. Select the snapshot’s Actions button and select Create Bookmark.
2. In the Create Bookmark dialog, provide the following information:
   • Bookmark Name — A name for the bookmark. DCT automatically generates a name based on the dSource name and timestamp (for example, dSource01-2026-05-07-15-07-24). You can edit this value.
   • Bookmark Visibility — Select one of the following:
     • Private: Visible only to accounts with permissions on this dSource.
     • Public: Also visible to accounts with permissions on compatible dSources.
   • Select Retention Date — Choose the date until which the bookmark and its associated snapshot are retained.
   • Keep until manually removed — Select this option to retain the bookmark indefinitely, regardless of the retention policy. This option is not recommended due to potential storage impact.
3. Select Create Bookmark.

The bookmark is created and appears on the Bookmarks tab of the dSource details page.
