Question
Which of the following technologies can successfully back up files that are used by other processes without stopping those processes?
A. Differential
B. Archive
C. Synthetic full
D. Open file
Answer
D. Open file
Explanation
Open file backup technology allows the backup process to capture files that are currently open or in use by other processes, without the need to stop or interrupt those processes. This is particularly useful in environments where critical files are constantly being accessed or modified, such as databases or shared files.
Here’s how open file backup works:
- Shadow copy: Open file backup creates a temporary snapshot or a shadow copy of the file being backed up. This snapshot represents the state of the file at a specific point in time.
- Backup: The backup process reads the data from the shadow copy instead of the original file. This allows the backup to capture the file’s contents without interfering with the processes accessing or modifying the original file.
- Consistency: After the backup is complete, the shadow copy is discarded, and the original file continues to be accessed by the processes without any interruption. This ensures data consistency and minimizes the impact on the running processes.
The other options mentioned in the question are not specifically designed to back up open files:
- Differential backup captures only the changes made since the last full backup, but it does not address the issue of backing up open files.
- Archive backup is used to create a copy of files for long-term storage or historical purposes, but it does not have built-in mechanisms to handle open files.
- Synthetic full backup combines the last full backup with subsequent incremental backups to create a new full backup, but it does not specifically deal with open files.
In summary, open file backup technology is the most suitable choice for backing up files that are being used by other processes without causing any disruption to those processes. It creates a temporary shadow copy of the file, allowing the backup process to capture its contents while ensuring data consistency and minimal impact on the running processes.
