Prepare before you upgrade. Check device support and free disk space, back up configs and snapshots. Use clear rule names, narrow objects and specific service ports. Enable logging and review hit counts. Test changes with connectivity, policy and regression checks. Automate exports and rule updates via the Sophos REST API for Sophos Firewall v22 configuration.
Sparse files let you create large logical files that consume little physical disk space until you write data. Use them for VM images, test files or temporary swap, but monitor actual usage with du and preserve holes when copying with cp --sparse=always or rsync -S.
I’ve used Linux Mint on client laptops and for sensitive files. Linux Mint security works fine if you configure it correctly. Treat the OS as a tool, not a guarantee. That means planning the disk layout, locking down networking, and choosing how and where to store legal documents. Read this as practical steps and examples […]
