Connect a large and fast portable hard drive. USB3 or eSATA is preferable.
Use rsync
to copy the Ahsay backup user's home directory to the portable drive.
Format and prepare the hard drive as EXT3.
This example command shows usage on a remote (from OBS) workstation PC using a non-standard SSH port and compression to improve speed over a WAN link:
rsync -avrz -e 'ssh -p 2222' --progress root@obs.domain.tld:/opt/obs/user/<name> /media/myusername/250GB-USB/
Omit this section for the standard SSH port 22:
-e 'ssh -p 2222'
rsync -avr --progress /opt/obs/user/<name> /mnt/250GB-USB/
Use the Decrypt Files Wizard from the OBM\ACB program.
Locate the path to the files, select the $BACKUPUSERNAME\files
folder and you should be able to restore from there.
