What are the advantages of a backup program?

Backup programs are indispensable when it comes to backing up your data and restoring it in the event of data loss i.e., caused by a virus, a hacking attack or hardware failure. To do this, a backup saves data on a suitable data carrier, e.g. an external hard drive or even in a cloud. This process is always the same, regardless of whether it’s a Mac backup or Ubuntu backup.

In addition to protecting your holiday photos, documents and other important files, backup software also offers other benefits:

  • Fast data recovery: In case data loss occurs, it can be quickly recovered from a backup.
  • Saves costs: A data backup program is significantly cheaper than professional data recovery offered by a service provider. Depending on which features are required or how high the security level should be, you can also find suitable backup software free of charge on the internet.
  • Data versioning: Some backup programs give you the option to save different versions of files. This allows older versions to be restored when needed, which is especially useful if you want access to them.
  • Restore flexibility: Data backup programs allow selective restoration. This means that you can select which files, folders or system elements to restore instead of restoring the entire backup.
  • Data archiving: Backup programs can also be used for long-term data archiving. This allows important data to be stored for a longer period of time without leaving it on the primary storage medium where it could be lost.
  • Unrestricted access: Online backup providers offer the additional advantage that your data can be accessed from anywhere. In addition, your files are in a safe place in the cloud and are therefore protected from theft, fire or [ransomware], for example.

IONOS Cloud Backup

In addition to automatic backups, IONOS Cloud Backup offers maximum security for your data through encrypted data transfer and ISO-certified data centres. Source: https://www.ionos.co.uk/cloud/cloud-backup

IONOS Cloud Backup offers a variety of features that allow you to back up your data to all your devices and restore it quickly and easily when needed. For this purpose, individual backup plans can be created with the help of the backup agent. You can decide when an automatic backup should be performed, how often and how long your data should be kept on the IONOS servers.

Other options include full image backup, versioning, antivirus and anti-malware scanning, and reliable protection against ransomware and cryptojacking. For maximum security, data transfers to ISO-certified IONOS data centres are SSL-encrypted. This protects the data from unauthorised access during transfer and when it’s in the cloud.

For fast data recovery, IONOS Cloud Backup offers several options, including selective recovery of individual files or folders and full system recovery. This allows you to recover the exact data you need without wasting time on unnecessary and lengthy recovery processes.

Another advantage is that the cloud backup’s storage capacity can be adjusted as needed, so you can simply add additional storage space as your data volume grows. In addition to packages with fixed amounts of storage space such as 50, 100 or 250 GB, you can choose the Flex package, where you only pay for the storage space you actually need (per gigabyte) each month.

Step-by-step instructions for setting up backup jobs can be used to reliably back up individual partitions or individual files and folders. In addition, you can save time and storage space by backing up only the changes that have been made since the last backup. With the paid version of the backup software, which already includes 1 TB of cloud storage, you can additionally transfer a system to another PC hardware.

With Ashampoo Backup Pro 17 you can easily create real-time backups of individual files, folders or entire drives as a Windows user. The backup program works in a resource-conserving way and goes unnoticed in the background.

In addition, you have the option of creating a backup plan, e.g. using the 3-2-1 backup rule, where you can specify which files should be backed up to which storage location. Choices include local or external drives as well as cloud storage such as Dropbox, Google Drive, OneDrive or Strato HiDrive. You can even set your own Owncloud, Nextcloud or Webdav server as the location. This means that your backed-up data is always available. For added security, you can version, compress, encrypt or password protect your data.

To save time and disk space, the backup software only creates copies of new or changed files after a full backup. If there’s a complete system crash, a previously created emergency USB stick can be used to restore your backup. Even carrying out a Windows 11 backup as a result of a system update is no problem for the program. Another advantage is that the backup software, which is fee-based, is regularly available at reduced promotional prices.

Aomei Backupper is a comprehensive backup program that is available free of charge in a standard version and a paid Pro version for Windows users.
