bu-usb_backup_tool

  1. Description:

BU is a program that makes keeping all of your user data safely backed up on a dedicated External USB drive easy. It is a leaner meaner version of the XBT backup script that came before it.

BU will update files that have changed, remove files that have been deleted and add any new files that have been created since the last backup. The initial backup can take a lot of time if you have a lot of data stored in your system's /home directory. BU creates a directory with the host name of the machine it's backing up from inside BU_Backups. This allows users to share one BU_Drive with multiple machines.

  1. Installation:

Unzip the "bu" bash script from the zip archive and move it to either /usr/local/bin or ~/bin. You can either do this from a command line or simply drag the file out of Archive Manager to wherever you'd like it to go.

Description:

BU is a program that makes keeping all of your user data safely backed up on a dedicated External USB drive easy.

BU will update files that have changed, remove files that have been deleted and add any new files that have been created since the last backup. The initial backup can take a lot of time if you have a lot of data stored in your system's /home directory. BU creates a directory with the host name of the machine it's backing up from inside BU_Backups. This allows users to share one BU_Drive with multiple machines.

The directory structure and all files are stored openly to allow users easy access if they only need to retrieve a few files or directories using a file manager.

The BU Restore function is an interactive tool that let's users restore their /home directories to a backup up state. This function will only work when restoring to a machine with the exact same hostname as the one the backs were made from. It is intended for emergency use, as when significant number of directories and files are accidentally removed from /home.

BU_Drive Setup

You need to prepare a BU Drive with a tool like Gparted or Disks. This can be any USB storage device. The dedicated USB drive MUST contain a partition formatted with a Linux native file system such as Ext4 or XFS. The partition MUST be labeled "BU_Drive" so BU can find it and use it for backups. The partition needs to have enough free capacity to store all data in /home on all of the machines you want to use the drive for. Note: You will get many errors if you attempt to use BU to backup to a partition that is formatted with non-native file systems like FAT32 or NTFS.
