Images - Do you backup to External or Internal Drive?

External, plus second backup in the cloud for some data (all encrypted), plus third (photos) on DVD once a while.
No images backup, data only.

 

External.

 

Both, I have a fairly elaborate backup strategy.

Nice article.

 

I backup Images mainly to internal hard drive with the occasional transfer of these Images to an USB hard drive.

 

Where's the option for both? I use the internal HDD for snapshots and external for weekly offline images.
