The short version

  • Each has a real cost: Amanda Enterprise minimum 10 workloads required for most use cases; Kopia space is only reclaimed when maintenance runs, and in a shared repository full maintenance is owned by one client, so if that machine goes away the repository grows for ever while every backup still reports success.
  • They diverge on capability: Amanda Enterprise covers Cross-platform backup, Kopia covers Content defined chunking.
  • Prices and features above were last checked on 31 August 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Amanda Enterprise

  • Minimum 10 workloads required for most use cases
  • Per-device pricing may increase costs for large deployments with many servers
  • Enterprise plan requires contacting sales for custom quotes
  • NAS/File share backups charged separately at $4.99-$5.99/TB/month after first 10 TB free

Kopia

  • Space is only reclaimed when maintenance runs, and in a shared repository full maintenance is owned by one client, so if that machine goes away the repository grows for ever while every backup still reports success.
  • The repository format has changed across versions and mixing client versions against one repository is discouraged, so a fleet must be upgraded together rather than machine by machine.
  • There is no central orchestration or reporting for many machines, so monitoring a fleet means building your own alerting around exit codes.
  • Restoring many small files is slower than the backup was, because content must be reassembled from pack blobs, and this is rarely tested until the day it matters.
  • Encryption is client side with no escrow, so a lost repository password means the data is unrecoverable and there is no vendor to appeal to.

Answered from the vendors’ own pages

Amanda Enterprise: How much does Zmanda Pro backup software cost?

Zmanda pricing starts at $5.99/month per device for the Business plan and $6.99/month per device for Business Plus with 24/7 support. Enterprise plans are custom-priced. Pricing estimator available at zmanda.com/pricing to calculate costs based on workload count and storage. Source: https://web.archive.org/web/20241128003646/https://www.zmanda.com/pricing/

Kopia: Is a partly corrupt repository still restorable?

Partly. Deduplication means one damaged pack blob affects every snapshot referencing its contents, but unaffected files still restore. Run verification regularly rather than assuming.

Amanda Enterprise: Is Zmanda's licensing model flexible?

Yes, Zmanda's licensing is flexible, you can change your server or client license midway if your backup environment changes and only pay the difference. Additional professional services cost $200/hour for consulting.

Source
Kopia: How does it compare with restic?

Similar guarantees, with packing that behaves better on per operation billing, a desktop interface, and compression enabled by default.

Amanda Enterprise: What payment options does Zmanda accept?

Zmanda offers multiple payment options including electronic fund transfers (EFTs), wire transfers, and credit card payments with flexible 1-year, 3-year, and 5-year license periods available.

Source
Kopia: Do I need to run maintenance manually?

It is scheduled automatically by default, but you must ensure the client that owns full maintenance keeps running, otherwise deleted snapshots never free space.

Kopia: Can several machines share one repository?

Yes, and that is where deduplication pays off, but they should run compatible versions and only one owns full maintenance.
