I recently installed the rom: http://forum.xda-developers.com/show....php?t=2285290
It includes AGAT_Recovery tREC_v0.3.5
I made a nandroid backup with it (it looks and functions identically to CWM). When I flashed back the EL26 ODIN one-click and tried recovery, the system image failed to flash. My question is: if I need to make a restoration with a system image created in AGAT_Recovery tREC_v0.3.5, is that image safe to restore with AGAT_Recovery tREC_v0.3.5?

Thanks for reading!

You must restore using the same kernel that you used to create the backup.

OK, so in every case the 'safe' recover is EL26 (Gingerbread). That is a different kernel than my current ROM runs. So basically, what do I need to do to nandroid backup & recover? Like I CWM failed when doing the above. Next time, are you saying that I:
EL26 CWM-->(flash kernel of ROM backup)-->(restore ROM)-->??

Yes, you can flash the Agat kernel from EL26 and then restore the CWM to restore the backup.
The Agat is a safe kernel and fine for backup & restore and flashing mods but many phones have issues with flashing entire roms with it (no need to flash a different kernel unless you are reflashing the rom) so we recommend using the older EL26 CWM or EL29 Directboot kernels just for when you're flashing JB roms. The only time you would need EL26 or EL29 is for flashing a fresh JB rom. This why you see instructions for flashing the Project X rom using EL26 or EL29 Directboot and the same applies to any custom JB rom.

Note: Of course, always follow the special flashing instructions that are provided for any custom rom.

So the basic procedure in this case would be (from Agat Kernel CFW) --> flash EL26 cwm --> Flash CFW kernel --> restore CFW

Am I understanding you correctly?

Not sure why the extra step there.
You created the backup with Agat, you have to use it to restore it too.
If that's what you said, then yeah go for it.

My only concern was with the the fact that the rom is indeed JB based. Thanks for the help
