The short version

  • Only Kopia has a free tier, so it costs nothing to try first.
  • Each has a real cost: Keepit search functionality is very limited with restrictive search strings and poor filter options; 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: Keepit covers Vendor-independent storage, 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.

Keepit

  • Search functionality is very limited with restrictive search strings and poor filter options
  • Download speeds during restoration are slow, particularly for mailbox restorations
  • Console interface is complex and unintuitive, making file retrieval time-consuming
  • Limited support for advanced features like Power Automate flows and manual backup job initiation
  • Primarily targets SaaS applications and is not a single platform for on-premises workloads, VMs, or endpoint backup

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

Keepit: What SaaS applications does Keepit protect?

Keepit provides backup for Microsoft 365 workloads (Teams, Exchange, OneDrive, SharePoint, Groups, Public Folders), Microsoft Entra ID, Google, Salesforce, and 15 SaaS applications total as of 2026, with plans to add more.

Source
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.

Keepit: How is Keepit priced?

Keepit uses custom pricing starting at $5 per seat monthly. Enterprise plans are custom quoted, with median annual contracts around $60,270. The pricing includes unlimited data storage.

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.

Keepit: Does Keepit guarantee immutability?

Yes, Keepit's architecture runs on secure, private infrastructure offering data immutability to prevent ransomware and accidental deletion.

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.
