For the last seven years, we have been using a Debian server installed with the ZFS filesystem. The server holds company's data served through sshfs, a dolibarr ERP, the company's website with Joomla and mail archives with dovecot. Data backup is done off-site with a rsync synchronisation. There are also five Ubuntu workstations. Thanks to Debian team for the fantastic work!
