incremental, differential, full incremental: backs up what has changed since the last full backup at increments of your choosing differential: backs up everything that has changed since the last differential backup full: backs up everything on your hard drive (WARNING: takes a long time and uses a lot of disk space)
There are several types of backup, including full, incremental, differential, and synthetic backups. A full backup copies all data to a storage medium, while incremental backups only save changes made since the last backup, and differential backups save changes since the last full backup. Synthetic backups combine data from previous backups to create a new full backup without needing to copy all data again. Additionally, cloud backups store data offsite, providing added security and accessibility.
Data backups
which two procedure can help secure data backups
The GDPR regulation requires that personal data be deleted upon request. This impacts the process of deleting data from backups because organizations must ensure that backups also comply with this requirement, which may involve implementing mechanisms to identify and remove specific data from backups when necessary.
Data files are data whereas data records are backups.
backups are needed for security reasons for any organization data is most important but if due to any reason (accident , virus ,human etc.) data get corrupt or get loss then it is big problem for organization there for these backups are needed
Best practices for backing up data include implementing a 3-2-1 strategy: maintain three copies of your data (one primary and two backups), store the backups on two different media types (e.g., hard drives and cloud storage), and keep one copy offsite to protect against physical disasters. Regularly test your backups to ensure data integrity and accessibility. Automate the backup process where possible to minimize human error, and establish a clear schedule for backups based on data criticality and change frequency.
The most important procedure that you can use to protect your software and data includes making frequent backups of your data. You should store the backups in remote locations
Cold(offline) backup / Hot (Online) backup, Logical backups using Exp and imp client utilities, RMAN Backups.
Backups that were made before the application of FileVault will not be encrypted. Backups made after the application of FileVault might be encrypted depending on how the backups were made.
The Cricket back up
There are a number of devices for remote data backups. These include the IDSBox and the IDSbox Mini. Websites such as PC Pro offer more information on remote backup devices.
