SEP sesam: the full review

SEP sesam offers a free, limited Community Edition and a quote-based commercial edition. Check the Community Edition's system and client limits against your backup needs before choosing it.

Overview

SEP sesam is backup software for computers and servers, with a mixed backup scope and several restore modes. It suits organizations that need a self-hosted option and can work within the Community Edition’s client and storage limits; its commercial edition is configured by quote.

The free edition’s bounded capacity makes it a practical starting point for smaller environments, but not a substitute for checking scale requirements before adoption.

Key features

SEP sesam supports computer and server backup, with ransomware protection and mixed restore modes. Its coverage across web, Windows, Linux, macOS, self-hosted deployments and an API gives it a broad platform footprint. That breadth is useful for teams protecting varied systems, though the Community Edition’s client and storage caps still constrain how much of an environment it can cover.

Pricing

Community Edition

The Community Edition is a free license for limited systems. It includes a 3 TB storage pool, 1 TB of Si3 deduplication, up to five backup clients and one bare-system-recovery license. Those caps give small deployments a no-cost way to use SEP sesam, but five clients and a single recovery license may be insufficient for broader or growing estates. Check the limits against both current backup needs and expected expansion.

Commercial SEP sesam

The commercial full product edition offers unit-purchase and subscription licensing, with a quote-based configuration. It is the option for organizations that need a commercial deployment rather than the Community Edition’s limited systems, but the price depends on the configuration.

Platforms

SEP sesam supports web, Windows, Linux, macOS, self-hosted deployments and an API. Its computer and server backup support makes it relevant to mixed environments, rather than only individual desktops or a single operating system.

Who it's for

Choose SEP sesam if you need backup for both computers and servers across varied platforms, and the Community Edition’s limits are adequate or you can pursue commercial licensing. Look elsewhere if you need more than five clients or one bare-system-recovery license without moving to a quote-based commercial edition.

Pros and cons

Pros

  • Broad platform coverage: support for web, Windows, Linux, macOS, self-hosted deployments and an API fits varied environments.
  • Free entry point: the Community Edition includes a 3 TB storage pool and up to five backup clients, useful for limited deployments.
  • Computer and server backup: it covers both, with ransomware protection and mixed restore modes.

Cons

  • Community Edition has firm capacity limits: it is capped at five clients, a 3 TB storage pool, 1 TB of Si3 deduplication and one bare-system-recovery license.
  • Commercial costs require a quote: teams cannot assess a standard purchase or subscription price from the stated terms alone.

Alternatives

For a broader comparison, browse Backup software or Virtual Machine Backup Software.

  • VM Backup is worth considering if a free forever edition limited to two VMs per host suits the workload, or if a 30-day fully featured trial is preferable.
  • Proxmox Backup Server may fit Linux and web environments; its Community plan costs 560.00 EUR per year and includes unlimited backup storage and clients.
  • Storware Backup & Recovery offers a free license without technical support and a 60-day trial for up to 20 virtual environments.
  • Veeam Agent for Mac is a narrower option for macOS; its free edition permits one backup job and does not back up directly to object storage.
  • Vinchin Backup & Recovery has a permanent free edition for up to three virtual machines, with Linux and Windows support.
  • Xen Orchestra is another option to compare.
  • Iperius Backup is a Windows option whose free edition supports Windows and Windows Server.
  • Uranium Backup has a free Windows edition for file and folder backup.

Verdict

SEP sesam is best for organizations seeking computer and server backup across mixed platforms, especially those whose needs fit the Community Edition’s five-client and storage caps. Its broad coverage and free entry point are compelling; the main reasons to look elsewhere are those hard limits or a need to know commercial costs before requesting a quote.
