.JRS File

What is a .JRS file extension?

A .JRS file is a reserve transaction log file. It is used by Microsoft Exchange Server to store transaction log information when the transaction log file runs out of disk space. .JRS files are created automatically by Exchange Server and are typically located in the Exchange Server database directory.

.JRS files are important for disaster recovery because they can be used to recover database transactions that were not committed to the database before the transaction log file ran out of disk space. However, .JRS files are not intended to be used as a permanent storage solution for transaction log information. If you are running out of disk space on your Exchange Server, you should increase the size of the transaction log file or move the database to a disk with more free space.
