Backup SME Server Remotely Using cURL (view source)
Revision as of 18:43, 11 June 2017
, 18:43, 11 June 2017→Scripting cURL and Improving Security
This HowTo describes a simple way to backup your SME Server remotely using cURL and requires no changes to your SME Server. Further, cURL requires no user interaction and can be scripted or automated using cron to perform regular backups. If the file system the backup is sent to is large file enabled (not DOS) this is also a fairly reliable way to get a desktop style backup > 4GB.
