Best Email Backup Tools for Gmail and Outlook (2026)

Most roundups on email backup compare download buttons — the wrong axis, and one that costs people mailboxes. A tool that exports an MBOX or PST file once is not a backup; it is a snapshot you took by hand and forgot to take again. Real backup runs on a schedule you did not have to remember, keeps versions you can roll back to, and lets you restore a single deleted message without touching the other 40,000.

This guide compares eight tools people reach for when searching best email backup tools for gmail and outlook — six dedicated backup platforms plus the two native export paths Google and Microsoft ship — and is honest about which are true backup, which are one-off exports, and where each fits. We build AI Emaily, an AI email client, not a backup product, so we are not in the table below. A short section at the end explains what a client like ours covers and why you still want a dedicated backup tool alongside it.

The short answer#

If you run a Google Workspace or Microsoft 365 tenant with real business mail — clients, contracts, invoices, anything you would regret losing — you want a dedicated SaaS backup tool that captures scheduled point-in-time copies and lets you restore individual items. Backupify (now Datto SaaS Protection), Spanning Backup by Kaseya, and Afi are the three most complete picks as of 2026. Backupify and Spanning are the incumbents; Afi is newer, with up-to-hourly capture and region-selectable storage as its sharpest differentiators.

For a solo user or family on personal Gmail, Outlook.com or IMAP wanting a free local archive, MailStore Home is the honest pick — free for private use, keeps everything on your machine, and reads every mailbox that speaks IMAP. To keep control of the backup server itself, CubeBackup runs on your own hardware and covers both Google Workspace and Microsoft 365.

If you only need a one-time copy — leaving a job, closing an account, handing a mailbox to a lawyer — Google Takeout and Outlook Export to PST do that in a few clicks. They are a dump, not backup, and are the right answer only for a dump.

How we compared#

The axis separating backup from export is one behaviour: what happens when you delete a message today, empty the Trash tomorrow, and want it back next month. With real backup, the message was captured before deletion, sits in a versioned copy on storage the provider does not control, and comes back in one restore action. With export, it is gone — because the last time you clicked Export was in March.

That behaviour splits the field cleanly. Dedicated backup tools (Backupify, Spanning, Afi, SysCloud, CubeBackup) schedule daily or intra-day captures automatically, keep version history, and offer granular restore. MailStore Home schedules captures too, with the archive on your own disk. Google Takeout and Outlook PST export are neither — a manual download of the mailbox as it exists right now, with no scheduler or restore path built in.

We also compared four secondary dimensions: which mailboxes are covered (Gmail, Microsoft 365, both, IMAP where relevant), where backup data is stored (vendor cloud, region-selectable, your own disk, your own server), restore granularity (whole mailbox, folder, single item), and packaging shape (per-user SaaS, one-off perpetual, free-for-personal, provider-native). No competitor prices appear below — those move. Check the vendor's pricing page before you buy.

Comparison at a glance#

Packaging shapes vary across per-user SaaS subscriptions (Backupify, Spanning, Afi, SysCloud), an annual per-user subscription on your own server (CubeBackup), free for personal use (MailStore Home), and native at no additional charge (Takeout, PST export). All of the paid options offer a trial; verify the current shape and price on the vendor's own page before buying.

Backup versus archive versus export — the shape that decides fit#

Once you look at the field this way, three shapes appear. Backup is scheduled, versioned, restorable. Archive is a searchable long-term store, often for compliance or space reclamation on the live mailbox. Export is a one-time file you keep somewhere. All three are useful, but they solve different problems and are not interchangeable.

A tool that only exports leaves you remembering to run it. A tool that only archives may not let you put a message back where it came from if a user needs it live again. Real backup does both jobs and adds version history that lets you undo a bad day. If you are choosing one tool for a business mailbox, backup is the shape you want; archive and export are supplementary.

1. Backupify (Datto SaaS Protection)#

Backupify is now sold as Datto SaaS Protection and covers Microsoft 365 (Exchange, OneDrive, SharePoint, Teams, Calendar) and Google Workspace (Gmail, Drive, Shared Drives, Calendar, Contacts). It captures three automated backups per day with point-in-time, granular, and non-destructive recovery — non-destructive matters because restoring an old folder copy does not overwrite what is currently there.

Licensing is per-seat with volume discounts and a 14-day trial. For managed service providers this is the incumbent — Datto's channel is why Backupify is the first tool IT partners recommend — and the administration console is built for MSPs managing multiple tenants, not a single-admin view.

Where it loses: if you want backup on your own infrastructure or in a specific region Datto does not offer, Backupify is not the tool. It is a vendor-cloud service by design — that is the price of the operational simplicity. Confirm current frequency, restore surface and pricing on Datto's product page before you commit.

2. Spanning Backup by Kaseya#

Spanning is the other SaaS backup incumbent — Google Workspace (Gmail, Drive, Calendar) and Microsoft 365 (Exchange Online, OneDrive, SharePoint, Teams) — with daily automated captures, on-demand runs, granular item-level restore, and a pipeline mature enough that billions of backups complete per week without stalling silently.

Packaging is per-user with a trial; Kaseya's FLEXspend lets larger customers reallocate spend across platforms — useful mid-migration. The console leans toward end-user self-service: an employee whose message got deleted can often restore it themselves without opening a ticket.

Where it loses: Spanning is a mature product and the interface shows it — closer to a business backup console than a modern SaaS app, with ransomware anomaly detection and storage-region choice less prominent than newer competitors. If those matter, weigh Afi in the same slot.

3. Afi#

Afi is the newer entrant, built for the axes incumbents undersell: capture frequency, restore flexibility, and where the data physically lives. It runs up to hourly automated backups for Microsoft 365 (Exchange, OneDrive, SharePoint, Teams) and Google Workspace (Gmail, Drives, Calendar, Contacts, Chats) — meaningfully finer-grained than the once- or thrice-daily incumbents.

Restore is item-level, either in-place or to another account (useful when the original user is gone). Storage region is a first-class option: US, EU (Netherlands and Germany), Switzerland, Australia, Canada and the UK — so a European tenant with data-residency requirements has an answer without self-hosting. Free trial, no card required; per-user annual pricing — verify on their site.

Where it loses: as the newest entrant, Afi's MSP ecosystem is thinner than Datto's and its procurement track record shorter. If channel support or vendor tenure is a hard requirement, weigh Backupify or Spanning instead.

4. SysCloud#

SysCloud sits alongside Backupify and Spanning as a multi-tenant SaaS backup with the same core coverage — Google Workspace and Microsoft 365 including Exchange mailboxes — plus a compliance and data-loss-prevention layer that other tools sell separately. If you need to both recover a deleted message and prove to an auditor you would have caught a policy violation, SysCloud puts both jobs on one console.

Backups are automated daily with on-demand runs; restore is item-level with a preview option; storage is on the vendor's cloud. Packaging is per-user with a free trial; compliance modules are often add-ons, not base-tier — read the plan carefully to know what is in the seat price.

Where it loses: without a compliance requirement, the extra layer is unnecessary complexity and a pure backup tool (Afi, Spanning) fits better. SysCloud is stronger when backup and policy monitoring belong to the same person; weaker when they are separate teams with separate budgets.

5. MailStore Home#

MailStore Home is a Windows desktop tool that pulls mail from any connected mailbox into a single indexed archive on your own disk. Sources include Gmail, Outlook.com, Yahoo, Microsoft 365, Exchange, Thunderbird, Classic Outlook (2003–2019), PST and EML files, and any IMAP or POP3 mailbox — the practical definition of everything a home user is likely to have. It is free for private use: no time limit, no feature gate, no per-mailbox charge.

Captures run on a schedule you configure, making it real backup rather than a snapshot, and the archive is fully searchable. Restore is item-level or by folder into any IMAP mailbox or Outlook — not a dead-end format if you switch providers. Because the archive lives on your own disk, back that disk up; a local archive on one drive is one drive failure from being no archive at all.

Where it loses: Windows-only, so Mac and Linux households need an alternative or a Windows VM. For business use, MailStore points to MailStore Server (per-mailbox licensed, out of scope here). For a Microsoft 365 or Google Workspace tenant with multiple users, the SaaS backup tools above are the right shape.

6. CubeBackup#

CubeBackup is the self-hosted option: install the server on your own hardware or a private cloud VM and point it at your Google Workspace or Microsoft 365 tenant. Microsoft coverage includes Exchange Online, OneDrive and SharePoint; Google coverage includes Gmail, Drive, Shared Drives, Contacts and Calendar. Backups run automatically, incrementally, and hourly by default, with unlimited version history for point-in-time restore.

The reason to choose CubeBackup over SaaS is storage control. Backup data lives on storage you own — a NAS, a local SSD, your own S3-compatible bucket — the right answer when your regulator or board requires that no third party holds a copy. Licensing is an annual per-user subscription (lower rates for non-profit and educational tenants); Shared Drives and SharePoint sites are covered without a per-seat charge.

Where it loses: someone has to run the server. If no one on your team is comfortable operating a small always-on VM, a SaaS backup is less friction end to end. The trade is real — you save the SaaS margin and gain full control, and you accept the operational responsibility of owning the box.

7. Google Takeout (native — export, not backup)#

Google Takeout is Google's built-in export path for a Gmail account (personal or Workspace, subject to admin policy). Pick Mail, optionally narrow to labels, choose a format — MBOX is standard — and Google produces a downloadable archive, usually within hours for a large mailbox. The MBOX output is readable by any mail client that supports it, so you are not locked into a proprietary format.

This is a one-off export, not a backup. Google does not schedule Takeout, keep version history, or offer an in-account restore path — the archive is a file you saved, and putting it back is a manual import. For leaving a job, closing an account, or handing a mailbox to a lawyer, Takeout is the right tool. For ongoing protection against deletion, ransomware or account compromise, it is not.

The honest use of Takeout is as a supplement, not a replacement. Even running one of the SaaS backup tools above, a quarterly Takeout to cold storage costs nothing and gives you a portable copy readable in ten years without a vendor account. Set a calendar reminder and treat it as belt-and-braces.

8. Outlook Export to PST (native — export, not backup)#

Classic Outlook's export path (File → Open & Export → Import/Export → Export to a file → Outlook Data File .pst) produces a PST of whichever folders you select. Any Classic Outlook client can re-import it into a live mailbox. For an on-premises Exchange, IMAP or POP account attached to Classic Outlook, this is the standard way to take a portable copy off the server.

Two limits matter. First, this is a manual, one-off export — Outlook does not schedule, version, or auto-restore it. Second, the New Outlook client (which Microsoft is nudging users toward ahead of Classic support ending in October 2027) does not support PST export. If your organisation has moved to New Outlook, this path is unavailable and you need one of the SaaS backup tools above.

Same framing as Takeout: PST export is a legitimate portable copy and a legitimate answer to 'I am leaving this account.' It is not a substitute for scheduled restorable backup on a business mailbox.

Where AI Emaily fits — and where it does not#

AI Emaily is an AI-native email client — triage, drafting, follow-ups, an approval-first agent — on Gmail, Outlook, iCloud and IMAP. It is not a backup product. We build AI Emaily, and stating we are the wrong tool for this job is more useful to you than putting our own row at the top of a backup comparison.

What we do genuinely help with: keeping the live mailbox in a state where backup restores are smaller and less frequent. Cold-email filtering keeps noise out so a compromised account has less payload to leak; approve-before-send catches a mistaken bulk reply before it needs rolling back; every agent action is logged and reversible so 'undo' handles most mid-day errors that would otherwise become restore requests. None of that replaces scheduled backup — it reduces the odds of needing one on a normal Tuesday.

The honest pairing: pick one of the SaaS backup tools above (Backupify, Spanning, Afi or SysCloud) for a Google Workspace or Microsoft 365 tenant, or MailStore Home for a personal mailbox on Windows, and use AI Emaily as the client on top. AI Emaily is on a 7-day free trial (Pro or Autopilot, card required, $0 if cancelled before day 7) — check current details on our pricing page.

How to choose for your situation#

Match the tenant shape first, then storage preference. Business tenant or personal mailbox decides which camp applies; vendor-held or self-held decides which tool inside that camp.

• Small business or team on Microsoft 365 or Google Workspace, no strong storage-location constraint: Backupify, Spanning, or Afi. Trial two of them side by side on the same tenant for a week and pick whichever the person who will actually operate it prefers.
• Microsoft 365 or Google Workspace tenant with a data-residency requirement (EU, UK, Switzerland, Canada, Australia): Afi has explicit region-selectable storage; CubeBackup lets you host in your own region entirely.
• You need backup on the same console as compliance and data-loss prevention: SysCloud. Weigh whether the compliance layer is base-tier or add-on before signing.
• You want the backup on infrastructure you own: CubeBackup — self-hosted server, per-user subscription, no third party holds the mailbox copy.
• Personal Gmail, Outlook.com, iCloud, or IMAP on Windows, free: MailStore Home. Remember to back the archive disk up too.
• You need a one-time copy for an offboarding, a legal request, or an account closure: Google Takeout for Gmail, Outlook Export to PST for Classic Outlook accounts. Neither is a backup — they are the right answer only for a dump.

How often should you back up an email mailbox?#

For a business mailbox on Microsoft 365 or Google Workspace, daily is the floor and intra-day (three-times-daily or hourly) is the right target if the tool supports it. The concern is not raw volume but the size of the loss window: if backup runs once a day at 2am and a wire-fraud attempt lands at 10am and is deleted from Sent at 10:30, a once-a-day backup would not have captured it.

For a personal mailbox, weekly is usually enough — loss scenarios are smaller and recoverable mail accumulates slowly. Set MailStore Home or your tool of choice to weekly and forget about it; let the built-in retention hold enough history that you can go back further if needed.

For every mailbox: keep at least three months of version history live, and take one longer-term cold copy per quarter in a format readable without a vendor account (MBOX from Takeout, PST from Classic Outlook, or the vendor's own portable export). That layer survives even a backup vendor going out of business.
