Apple’s documentation implies that you should not use Time Machine to backup photo libraries on that are located on external dirves.
“WARNING: If a Photos library is located on an external drive, don’t use Time Machine to store a backup on that external drive. The permissions for your Photos library may conflict with those for the Time Machine backup.”
I have been using Time Machine to backup an external drive, with photo libraries, and I have not receive any warnings or error messages.
Question: Will I be be able to recover or restore these photo libraries?
I want to make sure my photo libraries are safely backed up.
