Restoring Files
When selecting Restore you'll get a selection of backup files within your remote directory. After selecting your backup you'll see a Backup Set selection browser (version 1.5.0 or greater). This will show the name of each set in whatever backup you've chosen. This is a multi-selection box. You can select them all or just a particular one. Once selected the restore process will restore these files only. Versions older than 1.5.0 will restore everything in the backup you've selected.
During the restore process there are a few checks and post-run procedures to know about.
First, there is a version check. If you are restoring to a different version of Kodi than the one used to create the backup archive you'll get a warning. In most cases it is OK to proceed, just know that some specific items like addons and database files may not work correctly.
Next is a check is for an advancedsettings.xml file. If you've created this file and it exists in your restore archive you'll be asked to reboot Kodi. This is so that the file can be loaded and used for any special settings, mainly path substitutions, you may have had that would affect the rest of the restore. The Backup addon will prompt you to continue the restore process when you reboot the program.
The last bit of post-processing is done after all the backup files have been restored. By default this is when all the saved UI Settings from the backup will be set on the system. These are the things found in the Settings area of the Kodi menu. If you have the Always prompt to restore Kodi UI Settings setting turned on you'll get prompted on if you want these restored at the start of the backup. This process is done by comparing the saved settings with settings currently set via the JSONPRC Settings.SetSettingValue method. Only system specific settings can be restored so you will not get any custom views or skin specific settings back. If you're not seeing your addons, or other settings, see the FAQ for how to restore these.
