Setting up a progressive backup folder

Enable progressive backups of your hosted databases and specify the path to a folder used for progressive backup files. Progressive backups take place every five minutes.

Important  The progressive backup folder cannot be a parent or a subfolder of the default database folder, the backup folder, the additional database folder, or the Scripts folder. FileMaker Server attempts to open databases in the default database folder when FileMaker Server starts if the Automatically open databases that are in the database folders setting is enabled on the Configuration > General Settings tab.

To set up the progressive backup folder:

1. Click the Configuration > Folders tab.

2. Set Progressive Backup to Enabled.

3. For Progressive Backup Folder Path, click Change.

4. Enter the full path of the new progressive backup folder. The maximum length of the path is 255 characters.

Windows: The path you enter must start with filewin:/ and end with a slash (/).

For example, filewin:/driveLetter:/folderName/

macOS: The path you enter must start with filemac:/ and end with a slash (/).

For example, filemac:/volumeName/folderName/

5. Click Save. See Tips for valid folders.


Specify a progressive backup folder on a different hard drive from the one where the hosted databases reside. Since the progressive changes may be written to the progressive backup folder at nearly the same time that changes are written to the hosted databases, using two different hard drives may improve server performance.

Creating the initial set of backup files in the progressive backup folder may impact server performance. Once you have specified the progressive backup settings, avoid making changes to them. Any changes to the progressive backup settings require FileMaker Server to create a full backup of all hosted databases.

In rare cases, the progressive backup might fail if the machine's clock where FileMaker Server is installed changes by more than the save interval. FileMaker Server uses Coordinated Universal Time (UTC) for progressive backups; therefore, any time zone or daylight savings time changes do not impact the progressive backup.
