Data backup and recovery
Data backup and recovery are an integral part of computer information security. In the event of a system failure, an attack by intruders or other unforeseen circumstances, backup copies will help preserve valuable information.
What is backup?
Backup is the process of creating duplicate files and folders for later use in case of data recovery after possible loss or damage of the original files. The regularity of creating backup copies depends on the volume of changes in your system: you can make daily, weekly or monthly backups.
What data should be regularly backed up?
It is important to determine which data need constant updating through the process of registration (creation) of new versions of these objects.
– Documentation: text documents (.docx,.txt), Excel tables (.xlsx)
– Multimedia: photo, video
– Program code
Ways of execution:
1. Local storage - you can choose an independent download to an external medium (flash drive, hard drive) or use special programs for automatic creation of backup copies.
2. Cloud storage is the simplest and most convenient method of data backup. You can upload your files to a cloud platform such as Google Drive, Dropbox or OneDrive.
It is important to remember the following points:
1. Regularity: Create backup copies with a certain frequency - daily/weekly/monthly.
2. Multiple: Store several versions of backup copies in different ways (on a local drive and in the cloud).
3. Check data integrity after saving
4. Encryption: Protect data with a password
