Backing up your data properly is as important as collecting good data in the first place. As soon as you complete a project (or even during data collection), you should back up your data to a USB drive or to a laptop. Network connections are available to transfer data directly to a laptop. Many users are also transferring their data by ftp/sftp/scp to their home institution. This is only possible if you initiate the connection from BioCARS and then connect to the remote host. Your data cannot be accessed from outside of BioCARS.
Although users are ultimately responsible for backing-up their own data, BioCARS attempts to store the data for about 3 months. Please contact any staff member if you have additional questions.
Using The BioCARS Windows Computer
BioCARS has several computers running Windows 7 that can be used with your USB drive. This works for drives formatted as NTFS and FAT32.
- Log on to the computer using the appropriate username (userbmc or useridb) and the standard password.
- Connect the USB cable from the computer to your hard drive and then turn on the power to your drive. Windows should automatically recognize the drive and mount it if the disk is properly formatted.
- Your drive usually shows up on the desktop as a new icon. If not, you can find your drive through the Explorer interface. Your data can be accessed through the /data icons on the desktop. The data can be copied by the usual windows methods (copy and paste or click and drag).
- To disconnect your drive, select the icon in the taskbar (lower right) and “eject” your drive before physically removing the connection from the computer.
Using The BioCARS Linux Computers
USB under Linux is not as seamless as it is under Windows but it is improving. This should work for drives formatted as ext2, ext3, ext4 or FAT32.
- Log on to the backup computer with the appropriate username (userbmc or useridb) and the standard password.
- Connect the USB cable from one of the Linux boxes to your hard drive and then turn on the power to your drive. Linux should automatically open a window showing the contents of your drive. The data can be copied by the usual methods (copy and paste or click and drag).
- If you prefer working from a terminal, the drive is usually located in the “/media” directory.
- To disconnect your drive, you should find the icon on the desktop that represents your drive and right click on it. Select the “eject” option.
- You can now physically disconnect the drive from the computer.
Please remember to unmount (eject) your drive before physically disconnecting it from the computer. Otherwise there is a risk that your data may become corrupted.
A Laptop (both PC and Mac) can be connected to our internal network through DHCP. DHCP automatically assigns an unused IP address to your machine and allows you to copy your data to your laptop hard drive or an external disk connected to the laptop. Ethernet cables are available in the computer room and in the stations which allow you to access our network. The data is located on bm14cxf.cars.aps.anl.gov (for bmc) or on helix.cars.aps.anl.gov (for idb) and is typically accessed by using samba, nfs or ftp.
