Description
Backup of the configuration files allows recovery in case of corruption, misconfiguration, or catastrophic failure. The maximum number of rollbacks for the SRX is 50 while the default is 5 which is recommended as a best practice. Increasing this backup configuration number will result in increased disk usage and increase the number of files to manage. Organizations should not set the value to zero.
