The UNIX registry is a critical component for maintaining the integrity of backup and restore components and connectivity with the CommServe server. However, the registry can occasionally become corrupted due to improper shutdowns or file system corruptions, leading to potential data loss or connectivity issues. To mitigate this risk, Commvault implements a periodic backup mechanism for the UNIX registry, ensuring that the registry can be automatically restored to a functional state in case of corruption.
Key Features
-
Periodic backups, which serve as restore points in case of corruption.
-
The UNIX registry is backed up every 5 minutes to the directory /etc/CommVaultRegistryBackups.
-
Retention is based on the logic defined under backup pruning (see below).
-
-
Automatic restoration.
-
Every time the Galaxy script is executed, it evaluates the current registry for corruption.
-
If corruption is detected, the script automatically restores the registry using the latest available backup.
-
-
Backup pruning.
-
Older backups are periodically pruned to manage storage space and maintain a clean backup directory.
