Smart Repository

Periodic Data Backup
By performing data backup periodically, the environment can be restored even if information is altered
through unauthorized access. Periodic backup provides good protection against the following threats:
• Destruction or deletion of Smart Repository data
• Alteration of information recorded in files
• File destruction
Use the backup command (irepbacksys) to perform periodic backups. By periodically executing this
command, information prior to the destruction of protection target resources can be saved, and a
required generation can be restored even when resources are destroyed. For irepbacksys command
details, refer to "irepbacksys" in the Reference Manual (Command Edition).
Setting Access Rights for Files
If program files, resource files, data or other files comprising Smart Repository are destroyed or deleted,
services may stop or a program may be unable to start in Smart Repository. Setting appropriate access
permission for files is an effective measure to protect against such threats. Avoid unnecessarily
lowering the access permission levels that were set as initial settings.
