Hello, dear!
Good day to you!
In this post, I will show you how to backup/restore the system data of IVS1800.
Data backup improves device reliability. If a software or hardware fault occurs on the device, you can restore data to retrieve configuration files and recording files.
The IVS1800 supports automatic backup of configuration files, data coffers, and log files. Of course, if you want to back up manually, that's fine.
IVS1800 Backup Policy
The IVS1800 can automatically back up, Data Safe data, and log files.
Type of Data to be backed up | Default Backup path | default backup period |
Log files | /opt/Backup/logback | When each of five log files reaches 10 MB, the IVS1800 automatically performs compression and backup. |
Configuration files(Data safe) |
| Temporary backup directory Stores the latest backup of configuration files. If the configuration files have been backed up more than once, the latest backup will overwrite the earliest backup. Backup directory Stores the latest seven backups of configuration files. If the configuration files have been backed up for more than seven times, the latest backup will overwrite the earliest backup. |
Database files( Data Safe) |
| Temporary backup directory Stores the latest seven days of backup configuration files. If the configuration files have been backed up for more than seven days, the latest backup will overwrite the earliest backup. Backup directory Stores the latest seven days of backup configuration files. If the configuration files have been backed up for more than seven days, the latest backup will overwrite the earliest backup. |
How to check the RAID
The backup path of the configuration file depends on the RAID type. Check the RAID type on the IVS1800.
How to backup data
The IVS1800 supports the following backup modes:
Automatic backup
Configuration files
The system automatically backs up data at 02:05, 10:05, or 18:05 every day and backs up data only once every day. If you have manually backed up the data before the system automatically backs up the data, the data will not be automatically backed up on the current day.
For example, if a user starts the device at 03:00 and manually backs up data at 07:00, the system does not automatically back up data on the current 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 00:10. 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 a user performs a manual backup at 03:20, an incremental backup file will be generated at 03:20.
Manual backup
1. Log in to the OMU portal as the admin user.
2. Choose Maintenance > Data Safe.
3. Click Full Backup, as shown in the following picture.
Restore the data
Generally, the operating system and service software are normal. If the configuration is abnormal, you can use the Data Safe to restore data.
If the service software is abnormal, reinstall the service software and then restore the data.
If a hardware fault occurs, rectify the hardware fault and then restore the data. (Before data restoration, ensure that the version of the device with new subrack (referred to as the new device) is the same as that of the device backed up in the Data Safe.)
1. (Optional) If the device whose data is to be restored has been added to the hot backup group, remove the network cable from the device to disconnect it from the hot backup group, then connect the device to the computer, and set the IP address of the computer to be on the same network segment as that of the device.
2. Log in to the OMU portal as the admin user.
3. Choose Maintenance > Data Safe.
4. In the list of nodes whose data can be restored, select the backup data at a certain time point and click Restore.
Restored Data in the upper left corner is to restore the latest time point.
Restoration in the upper left corner is to restore the lost recording due to data restoration.
For example: if the current time is 18:30:00 on December 19, 2020, you can use data generated at 16:35:50 on December 18, 2020 to restore data. After the data is restored, you can click Restoration to restore the recordings generated at the two time points to prevent recording loss.
5. Enter the password of the current login user and click OK to verify the password.
The system automatically restores data in the following way:
a. The PWR indicator on the front panel turns from steady green to steady yellow, and the buzzer produces two beeps (for two seconds in total).
In this case, the device starts to restore data.
b. About 10 minutes later, the PWR indicator on the front panel turns from steady yellow to steady green, and the buzzer produces three beeps (for 3 seconds in total).
In this case, the data restoration is complete.
During data restoration, do not perform operations such as service configuration. The system will automatically restart the process. Ensure that the device is not powered off.
6. (Optional) If the device whose data has been restored is in the hot backup group, reconnect the network cable to the device to ensure that it is properly connected to the network.
7. After the data is restored, manually check whether the data is successfully restored and restore the recordings.
a. Log in to the OMU portal as the admin user.
b. Choose Maintenance > Data Safe.
c. In Operation, check whether data is successfully restored.
d. Click Restoration to restore the recordings.
Best wishes!
