Error handling
These options enable you to specify how to handle errors that might occur during backup.
Re-attempt, if an error occurs
The preset is: Enabled. Number of attempts: 30. Interval between attempts: 30 seconds.
When a recoverable error occurs, the program re-attempts to perform the unsuccessful operation. You can set the time interval and the number of attempts. The attempts will be stopped as soon as the operation succeeds OR the specified number of attempts are performed, depending on which comes first.
For example, if the backup destination on the network becomes unavailable or not reachable, the program will attempt to reach the destination every 30 seconds, but no more than 30 times. The attempts will be stopped as soon as the connection is resumed OR the specified number of attempts is performed, depending on which comes first.
Cloud storage
If the cloud storage is selected as a backup destination, the option value is automatically set to Enabled. Number of attempts: 300. Interval between attempts: 30 seconds.
In this case, the actual number of attempts is unlimited, but the timeout before the backup failure is calculated as follows: (300 seconds + Interval between attempts) * (Number of attempts + 1).
Examples:
- With the default values, the backup will fail after (300 seconds + 30 seconds) * (300 + 1) = 99330 seconds, or ~27.6 hours.
- If you set Number of attempts to 1 and Interval between attempts to 1 second, the backup will fail after (300 seconds + 1 second) * (1 + 1) = 602 seconds, or ~10 minutes.
If the calculated timeout exceeds 30 minutes, and the data transfer has not started yet, the actual timeout is set to 30 minutes.
Do not show messages and dialogs while processing (silent mode)
The preset is: Enabled.
With the silent mode enabled, the program will automatically handle situations requiring user interaction (except for handling bad sectors, which is defined as a separate option). If an operation cannot continue without user interaction, it will fail. Details of the operation, including errors, if any, can be found in the operation log.
Ignore bad sectors
The preset is: Disabled.
When this option is disabled, each time the program comes across a bad sector, the backup activity will be assigned the Interaction required status. In order to back up the valid information on a rapidly dying disk, enable ignoring bad sectors. The rest of the data will be backed up and you will be able to mount the resulting disk backup and extract valid files to another disk.
Re-attempt, if an error occurs during VM snapshot creation
The preset is: Enabled. Number of attempts: 3. Interval between attempts: 5 minutes.
When taking a virtual machine snapshot fails, the program re-attempts to perform the unsuccessful operation. You can set the time interval and the number of attempts. The attempts will be stopped as soon as the operation succeeds OR the specified number of attempts are performed, depending on which comes first.
