Just have to say something about Enhance backups. I've resolved some backup server problems (finally) and now I'm attempting to convert our WHMCS to Blesta. I set up Blesta on a separate website and created a manual backup so I can restore the freshly installed Blesta after migration attempt failures, and I'm so impressed with the speed of backup restoration!
It seems to be doing a delta between the backup and website so that only what is necessary is restored, which in my case is the Blesta database restored and nothing else.
My background with JetBackup which does incremental backups well, but full account restoration, especially for large accounts, must delete the account first and then restore the full thing. Enhance makes this so fast and easy! Color me ridiculously impressed but I have to say kudos to the Enhance team for this feature!
