# Note Revisions

Trilium supports seamless versioning of notes by storing snapshots ("revisions") of notes at regular intervals.

## Note Revisions Snapshot Interval

Time interval of taking note snapshot is configurable in the Options -> Other dialog. This provides a tradeoff between more revisions and more data to store.

To turn off note versioning for a particular note (or subtree), add `disableVersioning` labelto the note.

## Note Revision Snapshots Limit

The limit on the number of note snapshots can be configured in the Options -> Other dialog. The note revision snapshot number limit refers to the maximum number of revisions that can be saved for each note. Where -1 means no limit, 0 means delete all revisions. You can set the maximum revisions for a single note through the `versioningLimit=X` label.

The note limit will not take effect immediately; it will only apply when the note is modified.

You can click the Erase excess revision snapshots now button to apply the changes immediately.

Note revisions can be accessed through the button on the right of ribbon toolbar.
