Hello,
I’m testing the backup/restore process, and I found something annoying but non-blocking :
I have configure my discourse instance with the automatic daily backup on S3.
I made a fresh discourse install, created a new admin user, then go to Admin \> Settings \> Backups \> “Allow Restore”, so ready for Restore process.
Then I went to [aws.amazon.com](http://aws.amazon.com), downloaded the latest backup, and tried to upload it on my new instance.
Here is the blocking message :
> There has been an error while uploading ‘mydiscourseinstance-2015-04-02-030000.gz’: The backup file should be a .tar.gz archive.
Indeed, the backup is a “.gz” archive.
So I downloaded Z-zip for Windows 7, and created a .tar then a .tar.gz archive, uploaded it on my new instance. Here the welcome message :
> mydiscourseinstance-2015-04-02-030000.tar.gz’ has successfully been uploaded.
then … nothing 😱
“No backup available.” on the backup listing 😱
How can I restore my instance ?
Thanks for your help !

I think your browser changed the extension of the backup when you downloaded it. To fix it, you only need to change the extension back to “`.tar.gz`”.
As for the uploaded backup not showing up, you’ll need to make sure sidekiq is working by checking `you.discourse.org/sidekiq/scheduler` and making sure there’s no warning about sidekiq being paused.

Yes ! You’re right Régis ! 😄
After changing the extension to “.tar.gz”, I finally could restore the archive. Many Thanks ! (Sidekiq gave no indice)
So I’m facing a new trouble : the restore process didn’t restore my settings : logo url, s3 bucket for backup, baseline, etc, etc, etc
How can I save those kind of information ? If there is no other way, I will make some screenshots 🙂

The site settings are indeed saved in the backup. Due to how we cache them, you’ll need to restart the application for them to show up after a restore.

I’m glad you brought this up because I think I ran into the same thing. Not sure why downloading from Amazon S3 somehow replaces `.tar.gz` file extension with just `.gz` .. very odd.
@zogstrip should we accept both filetypes here? Is that safe, I have no idea.

Or maybe just use `.tgz` instead? ☀
It seems to be a generally accepted shorthand for `tar.gz`:

> tar is a file format and a file archiver program. The program combines multiple files into a single archive file in the tar file format. It was originally developed for magnetic tape computer storage – reading and writing data for a sequential I/O device with no file system, and the name is short for the format description "tape archive". When stored in a file system, a file that tar reads and writes is of...

Just allowed `.tgz` and `.gz` extensions for backup files 🐙
