Hello @Ajal 

These are Index Backups and should not be excluded from copy. What is the concern with them?

 

Thank you,

Hello @Ajal 

We will always keep 3 versions of the index in backups and the index backups will follow the data backups between copies. The index is metadata we generate about the backup data which is used for many things but for example browsing. We need to restore the index when you perform a browse (assuming the index is not in the cache). Without the index you cannot browse and restore the data.

You can refer to the documentation below for more detailed information.
