BFC DB Replica to a USB Thumb Drive

• Plug your USB thumb driver at the BFC server and ensure it is recognized by the OS while running fdisk command at the prompt (usually USB thumb devices are identified as sdbX)

  fdisk -l
  ….
  Device Boot      Start         End      Blocks   Id  System
  /dev/sdb1               1        1947    15633392    c  W95 FAT32 (LBA)
   
  

• Format the drive in a valid Linux FS by using mkfs.<FS_TYPE> command

  mkfs.ext3 /dev/sdb1
   
  

• Create a new mount directory (name it with something easy like “usbdrive”) and assign to it the USB device:

  mkdir /mnt/usbdrive
  mount /dev/sdb1 /mnt/usbdrive
   
  

IMPORTANT: In order to have your thumb drive mounted each time your server is restarted, you MUST edit the /etc/fstab file at the BFC. Simply add at the bottom of the file the following line

/dev/sdb1     /mnt/usbdrive     ext3     defaults 0   0

• For the troubleshooting give a restart to the BFC and run mount at the command prompt to verify your USB thumb is automatically mounted after server reboot

  [root@BFC backup]# mount
  /dev/mapper/VolGroup00-LogVol00 on / type ext3 (rw)
  proc on /proc type proc (rw)
  sysfs on /sys type sysfs (rw)
  devpts on /dev/pts type devpts (rw,gid=5,mode=620)
  /dev/sda1 on /boot type ext3 (rw)
  tmpfs on /dev/shm type tmpfs (rw)
  /dev/sdb1 on /mnt/usbdrive type ext3 (rw)
  none on /proc/sys/fs/binfmt_misc type binfmt_misc (rw)
  sunrpc on /var/lib/nfs/rpc_pipefs type rpc_pipefs (rw)
  nfsd on /proc/fs/nfsd type nfsd (rw)
  

• Access to the thumb drive with CD to /mnt/usbdrive and create a new directory (e.g. backup)

  mkdir backup
  

• Assign to the directory proper permissions:

  chown bfcadmin backup
  chmod 777 backup
  

  This directory is the location where the BFC will store the backup.

• At the BFC GUI set the DB replica path to /mnt/usbdrive/backup
