I use an HDD enclosure and it's getting full. Is there a way to use multiple HDD to make a backup?

Thanks.

Not sure if I understand some subtle thing in your question, but all you need to do is get another HD and plug it in. Reflect will see that there are no images on it so it will created a new Full. If you do incremental and differential images it will base them on that new Full when the drive is used.
If you plug in the other drive, it will base any incremental ore differential images you wish to create based on the existing images on that drive.
Ideally, you should always be using more than one drive and rotate them so if one fails you have another backup device that will be current or fairly close to current depending on your backup practice.

If you want to make multiple destinations a permanent part of your solution and have Reflect use whichever single destination is available at any given time, edit your definition file and click "Alternative locations" under the destination field to choose the additional desired destinations. I would recommend assigning your destination disks their own drive letters far down in the alphabet if you want to do this in order to avoid inadvertently sending a backup to the wrong device if the normal "next available" letter assignment mechanism causes an early letter you might currently be using to get assigned to something else at some point. (There's also a way to have Reflect target devices based on their unique volume identifier, but that's an application-wide change and may not be ideal.) Note that you'll only ever get one backup per execution, even if you have multiple destinations attached at the same time.

If you're asking about splitting a single backup across multiple devices, that technically is possible, but only for backups that are running interactively where you'll be able to see a prompt and specify a new destination. It doesn't work for scheduled backup that run in the background. But I can't say I'd recommend that strategy.

What I mean is when the disk is full, can I remove my full HDD from the enclosure, put another HDD in it, in order to complete by backup, like I would call it a set.

Technically yes, but not during a scheduled backup that runs in the background. But I personally would try to avoid splitting backups across HDDs. On top of the additional organizational hassle, a loss/failure of either disk now means you’d lose the ability to use backups on other disks too.

Consider using a retention policy that is sensible for the source data quantity and destination capacity you’re working with, and allowing Reflect to purge older backup sets when disk space drops to a certain level.
