TWRP - What's "Release Keys"?

I've got a folder that's called "Backups" and inside that one called "SH441WM05104"

Inside that folder there are three folders, called

2015-06-19--16-19-08_LRX22C_release-keys (8,7 GB)
2015-06-29--08-13-51_LRX22C_release-keys (9,6 GB)
2015-07-29--08-27-11_LRX22C_release-keys (10,46 GB)

Why are they called "release keys"? It seems like they are ordinary TWRP backups.
 
Those would be your backups. Custom Roms (and kernels) use test-keys, stock uses release-keys. This is an over simplification, but that's the way TWRP names the backups.
I'm pretty sure it's "DATE-TIME-BUILD"
So for the last one July 29 2015 - 8:27AM and LRX22C with an official signature.

I may be off or oversimplifying, but that's the gist. Sorry nobody replied before, hope this helps.

Anyone, feel free to correct my bad description, even though the post is old it may answer someone's question in the future.

Thanks for replying in here Dan and welcome to AF!

I'm sorry I missed this thread--I usually monitor this forum area but don't remember seeing this thread back in June...

Pretty sure TWRP uses the system property "ro.build.display.id" to append to the date/time in building the last part of the backup folder name.

The format of the backup folder name is:

<external storage path>/TWRP/BACKUPS/<device serial #>/<date/time>_<ro.build.display.id>​

See the TWRP source for how the above backup path name is built:

Cheers!
 
NP. Been around here and there since the days of the HTC Hero, just don't usually participate in discussions. I try to help where I can, and try to stay out of the way of the real smart folks.
