Never lose your data — make regular backups
What Is a Backup? Data Protection and Site Recovery
A detailed explanation of backups — types (full, incremental, differential), the 3-2-1 rule, automatic vs manual backups, and how BeoHosting protects your data.
What is a backup and why is it critical?
A backup is a copy of your data (files, database, emails) stored in a separate location. It protects against hacker attacks, ransomware, code errors, hardware failure and human mistakes. The 3-2-1 rule: 3 copies, 2 different media, 1 off-site. Without a backup, lost data is gone for good. BeoHosting creates automatic daily backups with 30 to 120 days of retention, depending on the plan.

What is a backup and why is it critically important?
A backup is a copy of your data stored in a separate location that lets you recover everything in the event of loss. For websites, a backup covers your site files (HTML, images, themes, plugins), the database (content, users, settings) and email messages.
Think of a backup as an insurance policy for your data. You hope you will never need it, but when your site gets hacked, when you accidentally delete important files, or when an update breaks something — the backup is the only thing standing between you and total loss.
Statistike kažejo, da 60 % malih podjetij, ki izgubijo podatke, preneha poslovati v 6 mesecih. BeoHosting izdeluje samodejne dnevne kopije vseh gostovalnih računov s hrambo od 30 do 120 dni, dodaten prostor za kopije pa je na voljo uporabnikom, ki želijo dodatno zaščito.

How does a backup work?
The backup process has four key steps — from creating the copy to restoring the data:
Creating the backup
The system (automatically, or you manually) creates a copy of all site files and the database. A full backup copies everything, an incremental copies only changes since the last backup, and a differential copies every change since the last full backup.
Compression and encryption
The backup is compressed to take up less space (typically 3-5x smaller than the original) and optionally encrypted to protect the data. Encryption is especially important for off-site backups stored in the cloud.
Storage in a separate location
The backup is kept on a separate disk, server or cloud storage (such as AWS S3 or Google Cloud). According to the 3-2-1 rule, at least one copy should be in a physically remote location from the original server.
Restore (recovering data)
When needed, the backup is decompressed and restored to the server. You can recover the entire site, just the database, or even individual files. A good backup system allows granular restores.
Why a backup is irreplaceable
A backup is the last line of defence for your data — without it, loss is permanent and irreversible.
Protection against data loss
A backup protects against data loss caused by hacker attacks, ransomware, code errors, failed updates or accidental file deletion.
Fast site recovery
When something breaks, a backup brings the site back to a working state in minutes. Without a backup, rebuilding a site can take days or weeks.
Ransomware protection
Ransomware encrypts your data and demands a ransom. With an off-site backup you can ignore the attacker and simply restore your data. A backup is the best defence against ransomware.
Freedom to experiment
When you have a backup, you can freely test new plugins, themes or updates without fear. If something goes wrong, you simply restore the previous version from the backup.
Compliance and regulation
Many industries require regular data backups (GDPR, PCI DSS). Automatic backups with provable retention help you meet regulatory requirements.
Business continuity
For business sites, every hour of downtime costs money. A backup ensures minimal downtime and continuity even after a serious incident.
Types of backup
There are three basic types of backup, each with its own advantages and drawbacks:
Full backup
Copies all data every time. The simplest to restore, but takes the most space and the longest to run. Ideal as a weekly backup that serves as the basis for incremental backups.
Incremental backup
Copies only the data that has changed since the last backup (of any type). The fastest and takes the least space, but a restore requires a full backup plus all incrementals up to the desired date.
Differential backup
Copies all data changed since the last full backup. Larger than an incremental, but faster to restore (you only need the full plus the latest differential). A good compromise between speed and reliability.
The 3-2-1 rule
The gold standard for backup strategy: 3 copies of the data, 2 different media, 1 off-site copy. Example: original data on the server + a backup on a separate disk + a backup in the cloud (AWS S3).

A backup is a copy of your data (files, database, emails) stored in a separate location. You need it because data can be lost to a hacker attack, a code error, hardware failure or human mistake. Without a backup, lost data is gone for good.
What is the 3-2-1 backup rule?
The 3-2-1 rule means: keep at least 3 copies of your data, on 2 different media (e.g. server + cloud), with 1 copy in a remote location (off-site). This ensures that even in a disaster (fire, flood) you still have your data saved elsewhere.
What is the best backup type for a website?
For most sites, a combination of a full weekly backup and daily incremental backups is optimal. A full backup keeps a complete copy, while incrementals store only the changes since the last backup, saving space. BeoHosting automatically creates daily backups with 30 to 120 days of retention (depending on the plan).
Does the hosting provider back up my site?
Most quality hosting providers create automatic backups. BeoHosting backs up all hosting accounts daily. However, we always recommend keeping your own backups as extra protection — never rely solely on the provider's backup.
How often should I make a backup?
The frequency depends on how often your content changes. For active blogs and e-commerce sites — daily. For brochure sites that rarely change — weekly. For critical business applications — every few hours, or even in real time (real-time replication).
