Compression

In this article you will learn about compression in Xopero ONE.

Understanding compression

Compression is the process of reducing the size of data before it is stored in a backup. It minimizes storage usage and can improve transfer speed by decreasing the amount of data that needs to be written or transmitted.

In Xopero ONE, compression is enabled by default to reduce the time needed to transfer backup copies to storage and to minimize the storage space needed to keep them.

Configuring compression settings

Compression can be enabled when creating a new backup plan in XMS. You can find it in the backup plan's advanced settings (Advanced settings > Edit > toggle the Compression option to enable it).

Unlike encryption and deduplication, compression settings can also be adjusted in an already existing backup plan.

Depending on the type of data being backed up, you can choose between two compression algorithms:

1. LZ4 — fast compression with a reasonable compression ratio.

2. Zstandard — lossless compression algorithm, used in Xopero ONE by default.

And also three compression levels:

1. Normal — compression is faster, but the data takes more storage space.

2. Medium — the most optimal level with the best balance between processing time and storage space usage; used by default.

3. High — compression takes longer, but the data requires less storage space after compression.
