I've been looking for an app to do scheduled, encrypted backups to my remote FTP server. I wanted something reasonably fast and the ability to do versioning would be nice.
I was about to give up and settle for something that was fast and could encrypt backups (but no versioning) when I finally decided to try SuperFlexible. I confess to having been put off by its appearance - not very "Mac-like." Well, SuperFlexible is VERY flexible and rather impressive in its long list of customizable features. But it wasn't as fast, seemingly, as the app I was starting to settle on. So I wrote the developer and asked about SuperFlexible's ability to copy multiple files in parallel. That was last night. This morning I got a reply (on a weekend, no less) that told me exactly what I needed to do ("specify the number of files to copy in parallel on the Files tab sheet in the profile"). It worked like a charm! Now SuperFast copied my test folder in LESS time than the other app!
It's so fast that I copied a huge folder of folders of files (2.2 GB worth) in less than 2 hours. Much faster than I was expecting. And I don't think I've gotten all the optimizations set yet, either...
I should mention that SuperFlexible is pretty intuitive in its operation. There's even a "wizard" mode which I didn't use since it's pretty easy to use (in "advanced" mode) anyway.
SuperFlexible encrypts using zip files. You specify the password and SuperFlexible does the rest. I tested by using YummyFTP (another great program) to copy back, from the remote, one backed-up file that was zipped. I used Springy to unzip the file. Springy asked for the password, which I gave, and voilà! I had my original, unencrypted file back. Of course SuperFlexible will automatically decrypt files when you fetch them back, but I wanted to do the test without that in case I'm ever stuck without it.
What else? SuperFlexible communicates with remote servers via FTP, SSH, WebDAV, Amazon S3, Google Docs, and Azure (not sure what that is... ;-) There's a LOT more settings for scheduling, masking/filtering of transfers - way more than I can describe here.
Bottom line: I like it!
