Remote backup options have been redone so you can now upload to multiple different backup services at once. So you can have your remote backups upload to both Amazon and BackBlaze at the same time if you wanted to. You will need to re-enter your remote backup options for this new version.
The Amazon SDK had to be updated in order to resolve an issue that occurred due to XF2.2 upgrades. I don't know if Amazon S3 backups will still work on XF2.1 after this. Let me know.
BackBlaze meta notes will no longer list the secret app key in the file.
The "Remote options" section has been completely rewritten. As such, you will need to redo all your options in this section after upgrading. If you don't, remote uploads will fail, and possibly produce errors.
BackBlaze has been added as a remote upload option!
Dropbox has been added as a remote upload option!
Fixed an issue related to Guzzle duplication in XF2.1.
While this addon really has no issues with this announcement. I felt it would probably be wise to mention it in this update. If you are having issues related to the announcement, you can simply add --default-character-set=utf8mb4 to the "MySQL options > Custom dump options" field in the options for this addon. I have also made this the default setting for this field for future installers.
This addon will no longer re-open your board after running a backup, if your board was closed originally. It will retain the open/close setting of your board at the time the backup began.
Added a few explanations for the Amazon S3 fields in the options to help people figure it out.
