Database Backup Manager - ERROR

[dome90uk]

Hi,

Am am currently upgrading my store to 1.3.9f and have just installed the Database Backup Manager. The DBM page in admin is now showing the following error:

Error ERROR: This backup script seldom works when safe_mode is enabled or open_basedir restrictions are in effect.
If you get no errors doing a backup, check to see whether the file is less than 200kb. If so, then the backup is likely unreliable.

This error does not show up my 1.3.8a store.
The two stores are on the same hosting / setup.

I have made a backup and everything seems to have worked OK. I have not tried a restore yet as I would like some advice first.

Any help appreciated
