GMvault vs SysTools Email Backup Wizard

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.

SysTools Email Backup Wizard backs up email accounts and exports messages as PST, MBOX, EML, MSG, or PDF files. The product page lists more than 225 supported services, including Gmail, Outlook.com, Yahoo Mail, Zoho Mail, AOL Mail, iCloud Mail, GMX, Rediffmail, GoDaddy Webmail, Zimbra Mail, RoundCube, and other IMAP servers. Date filters, incremental backup of new mail, automatic retries, and resuming interrupted jobs are available. SysTools says folder hierarchy, attachments, headers, timestamps, and read status are preserved. Destinations include local drives, USB devices, mapped network locations, and NAS paths. OAuth 2.0 sign-in is supported for Microsoft 365 and Gmail, without storing those passwords, according to the maker. Windows and macOS versions are offered. The demo handles up to 100 items from the first five folders. Full Version License (Windows) costs $5 per user, billed once, with five users minimum and $25 total.
