Backing Up Data

Default Backup Policies

The system can automatically back up configuration files, Data Safe data, software packages, and log files.

Context

Data Safe

The Data Safe is a software system running in the HWT-IVS1800. It periodically backs up configuration files, database files, and software packages.

The HWT-IVS1800 supports the following backup modes:
  • Automatic backup
    • Configuration files

      The system automatically backs up data once at xx:05 (for example, 01:05) every day.

    • Database files

      The system automatically backs up data 24 times a day at an interval of 1 hour. The first backup is performed at 00:05. The first backup is full backup and subsequent backups are incremental backup. The number of backup files increases each time a manual backup is performed. For example, if you perform a manual backup at 03:20, a full backup file will be generated at 03:20.

    • Software packages

      The system automatically performs full data backup at xx:05 (for example, 01:05) every day only when the software package is changed.

  • Manual backup

    For details about how to manually back up data, see Manually Backing Up Data.

Log files

/opt/Backup/logback

When each of five log files reaches 50 MB, the HWT-IVS1800 automatically performs compression and backup.

For details about log file storage rules, see Log Processing Principle.

Data Safe data:
  • System disk directory
    • Database file backup directory: /opt/Backup/$index_YYYYMMDD/DataGaussdba
    • Configuration file backup directory: /opt/Backup/$index_YYYYMMDD/DataSafeCache
    • Software package backup directory: /opt/Backup/base_$software version
  • Data disk directory
    • Non-RAID mode: /mnt/dir_*/backup
    • RAID mode: /opt/SmartData_D/G0_*

    In both modes, data is backed up only to the first four hard disks.

Ensure that the available space of the system partition is greater than 15 GB. If the capacity of the backup set exceeds 50 GB, the system clears the backup set by day until the number of backup sets is less than or equal to 7. The upgrade backup set is stored for seven days. After seven days, the upgrade backup set is deleted based on the common backup set clearing policy.
