What is the maximum number of rollback files a Junos device can store?

In Junos OS, the system keeps a history of configuration changes to allow users to revert to previous configurations if needed. The maximum number of rollback files that a Junos device can store is indeed 50. Each rollback file represents a snapshot of the system’s configuration at a particular point in time, which users can utilize to quickly revert to an earlier state without needing to manually change settings or access backups.

This capability is particularly useful for administrators, as it provides a safeguard against misconfigurations or errors during configuration changes. By having several rollback options, users can effectively manage and recover from various states of the system, ensuring a higher level of operational reliability.

The number is capped at 50 in Junos to balance the available storage with the need for configuration backups, allowing adequate recovery points without excessive use of system resources.
