Aryson Email Backup Wizard vs GMvault

Aryson Email Backup Wizard backs up or migrates mailbox data from web and cloud email accounts, saving messages and attachments to local or external drives. It supports more than 50 mailbox types, including Gmail, G Suite, Office 365, Yahoo Mail, iCloud, Zoho Mail and IMAP accounts. Export formats include PST, MSG, MBOX, EML, EMLX, HTML, PDF, CSV, RTF, XPS, DOCX and JPEG, among other document and image formats. Mail can also be moved directly to services such as Gmail, Office 365, Hotmail, iCloud Mail, Zoho Mail and Google Workspace. Batch Mode uses a CSV of account credentials to process multiple mailboxes; users can select folders, filter by date, preview items and skip duplicates. Further controls include splitting PST output and saving attachments separately or omitting them. The free version exports 50 emails per folder, while the full version removes that stated limit. Downloads are offered for Linux, macOS and Windows. A free plan and trial are listed; pricing starts at $119. Aryson lists free technical support 24x7.

GMvault backs up Gmail accounts to help preserve email correspondence and can restore a local email repository to Gmail. It offers full synchronization as well as incremental quick synchronization. The tool runs from the command line and is described as user-friendly. XOAuth is enabled by default as the recommended sign-in method; its token is stored in $HOME/.gmvault after first authentication. Users can alternatively sign in with a Gmail password, which is encrypted if they choose to save it. Emails are stored by default in $HOME/gmvault-db, or %HOME%/gmvault-db on Windows. Restore operations include --resume and --restart options for avoiding re-upload of emails already processed. GMvault is free and open source under GNU-AGPL-3.0, with Linux, macOS, and Windows support. The project documents binary installs for those systems and installation from source through Python setup.py, pip, or easy_install. PyPI lists version 1.9.1, published March 31, 2016.
