Artlook automatically backs up your data every night including your uploaded images. Backups are kept for 4 days.
However, the intention of these backups is to prevent against server or internet failure and not to mitigate for data entry errors. As a belt and braces you can if you wish choose on a regular basis to Export your data (menu item on the System Menu) and keep a local copy. This will download the data in spreadsheet format (images are not included as it is assumed you will maintain the original that you uploaded).
Artlook is not a secure image repository. However we do offer such a service as an option, whereby you may upload very high quality large images and they will be kept securely and accessible for you. Please contact info@artlooksoftware.com for more details of this service.
