[BUG] Missing dir && file for backup

[psstoyanov]

Description

With the first update to 1.0.2 from 1.0.1 , the system strongly encourages the user to backup the system.

However, the backup can't be created.

Details

Looking at the logs:

• When initiating the backup, the user is presented with the following message
  

The actual report from uart indicates that the expected directory and archive file are not present:

missing /rcade/share/.emulationstation/backups/rootfs_backup.tar.xz

tar: Removing leading `/' from member names
tar (child): /rcade/share/.emulationstation/backups/rootfs_backup.tar.xz: Cannot open: No such file or directory
tar (child): Error is not recoverable: exiting now
tar: /rcade/share/.emulationstation/backups/rootfs_backup.tar.xz: Cannot write: Broken pipe
tar: Child returned status 2
tar: Error is not recoverable: exiting now

• Manually creating the directory and an empty file with the expected name allows the process to proceed
  

created missing dir and file allow for the process to proceed

# mkdir backups
# cd !$
cd backups
# pwd
/rcade/share/.emulationstation/backups
# touch rootfs_backup.tar.xz 
# tar: Removing leading `/' from member names    # Indicating that the process has begun

Running this over SSH before starting the back up will resolve this, and a fix for this will be included in the next release :) Thank you for reporting this!

mkdir -p /rcade/share/.emulationstation/backups

Resolved in 1.0.3
