Default Restore Backup - SMS etc.

Hi everyone,
i hope someone can help me out with the following:
-Before moving to a new phone i've backed up data with an application....(i didn't do myself)
-After trying to restore it looks like the files are not good to be restored.....the fact is that the apps used to back up probably has not been reinstalled and the person now is not able to remember which one he used.
The file format for info,SMS etc. is .txt
and the file structure inside is something like:
{"subCategoriesSms":[{"address":"
"smsType":"TYPE_INBOX","status":"-1","checked":true,"label
if i could understand which backup apps use this set probably i could re-import.
-The phone where the backup was created was rooted, the new one is not....
Hope someone has a clue!
