Comparison Table
Shoviv IMAP Backup Tool
enterpriseCreates local backups of IMAP mailboxes with incremental backup support.
Folder-aware IMAP export that maintains hierarchy in offline backups for targeted restores.
Shoviv IMAP Backup Tool fits environments that need reliable backups of IMAP mailboxes onto local destinations for retention workflows and restoration testing. The workflow supports connecting to an IMAP server, enumerating folders, and exporting messages into offline-friendly formats suitable for later processing. The utility’s practical strength is repeatable export behavior for ongoing mailbox protection rather than one-time extraction only.
A tradeoff is that IMAP backup throughput depends on server responsiveness and network latency because message retrieval is performed in batches over IMAP. It is also a better fit for teams that want file-based archives for later handling instead of mailbox-level policy controls inside the source system. A common usage situation is recurring backups for a small to mid-size domain where restore drills are run against exported data.
- +Preserves folder hierarchy in exported archives for easier later recovery
- +Supports repeat backup runs for ongoing mailbox protection workflows
- +Provides multiple authentication options for common IMAP deployments
- +Exports messages into offline formats for later review pipelines
- –Performance varies with server response and batch download behavior
- –Backup success depends on correct IMAP permissions and access scope
- –Large mailboxes require staged runs to reduce operational risk
- –Limited visibility compared with enterprise backup suites for fleet governance

Best for: Fits when mid-size IT teams need repeatable IMAP exports for retention and restore testing.
MailStore Server
enterpriseEnterprise email archiving software supporting IMAP server integration.
Legal hold workflows combined with chain-of-custody style logging for archive actions tied to mailboxes.
MailStore Server focuses on on-premise IMAP mailbox archiving with incremental sync that keeps archived copies aligned with mailbox changes. It supports MBOX archive and EML extraction, which helps teams move data into e-discovery workflows or offline storage.
MailStore’s folder hierarchy mapping and message flag preservation reduce breakage when users expect IMAP structure and read states to carry into the archive. Administration supports scheduled jobs with batch download and retry-on-failure behavior for long-running mailbox imports.
- +Incremental sync keeps archives current without full re-downloads
- +MBOX archive output and EML extraction for downstream tooling compatibility
- +Folder hierarchy mapping preserves IMAP structure and navigability
- +Message flag preservation reduces user-visible drift between live and archived mail
- –Requires careful configuration of connection, throttling, and retry behavior
- –OAuth2 authentication coverage depends on the mail source integration profile
- –High mailbox volumes can stress throughput during batch fetch and indexing
- –Governance reporting needs separate operational process for review and retention

How to Choose the Right Imap Backup Software
The options differ most in how reliably they back up IMAP mailboxes over time. Pay attention to criteria like Consistent mailbox coverage, because that determines whether your archive still matches what users see in production.
Consistent mailbox coverage
Why it matters
Consistent mailbox coverage matters because “missed” messages are hard to notice after the fact. If backups don’t stay complete across runs, you cannot trust restores.
How to check
In a demo mailbox, run a backup twice with no user changes and compare the message count and receipt timestamps. Then create a small test message and run again to confirm it appears in the next backup set.
Restore testability
Why it matters
Restore testability matters because an IMAP backup is only useful when you can bring mail back in a verifiable way. Better restore controls reduce the risk of partial or scrambled recovery.
How to check
Ask the vendor to show a restore workflow to a target mailbox or export. Use a message you can identify (subject + date) and confirm it lands in the expected folder with the same headers and body content.
Folder and state mapping
Why it matters
Folder and state mapping matters because mail often relies on folders and user state to stay usable. If the tool changes placement or loses message markers, users will see “wrong” mail after recovery.
How to check
During a demo, back up a mailbox that includes multiple folders plus at least one message in a non-default folder. Restore and verify the folder names and key message attributes you care about remain intact.
Change detection and incrementals
Why it matters
Change detection and incrementals matter because they determine whether scheduled runs are accurate and fast. Poor incremental logic can duplicate content or skip updates.
How to check
Run one full backup, then add and delete a small number of messages. Schedule an incremental run and check whether the backup history shows only the new/removed changes without duplicates or missing items.
Scheduling and automation control
Why it matters
Scheduling and automation control matters because mailbox backups must run without constant babysitting. Strong automation also makes it easier to meet internal retention and audit expectations.
How to check
Ask how the scheduler handles missed windows and retries, and whether you can control concurrency and run order. Confirm you can export a run report that includes mailbox, time range, and result status.
Audit logs and run visibility
Why it matters
Audit logs and run visibility matter because they help you prove what was backed up and when. When an issue happens, these logs cut the time to find the faulty mailbox, run, or configuration.
How to check
In a demo, trigger a backup for one mailbox and then locate the run record in the UI or API. Check that it includes start/end times, mailbox identifier, counts, and an error detail view for failures.
Red flags
- Backups succeed but message counts change across repeated runs
- Restores place messages in unexpected folders or alter key headers/states
- Incremental runs create duplicates or omit newly added mail
Fit by situation
- If you need backups that stay complete across weeks of normal mailbox use, prioritize Consistent mailbox coverage.
- If you expect to test recoveries before an incident, prioritize Restore testability.
- If your team runs scheduled jobs and must prove what happened, prioritize Audit logs and run visibility.
