Back Up

From X6AWiki

The data being collected at X6A beam line could either be FTP'd to another computer or backed up for further processing.

If you choose to go the FTP route, telnet must pass through proxies. Following are the options to backup your data.

Contents 1 Using Anonymous FTP 2 FTP through proxy 3 Backup to Laptop Computer 3.1 Data Transfer Using FTP 3.2 Data Transfer Using SCP 4 Taking Backup on the DVD Media 5 USB and Firewire 6 Taking Backup Using FireWire 7 Taking Backup Using USB2.0

Using Anonymous FTP

For users who need to transfer their data files from NSLS to their institution at later point of time, we have setup an anonymous FTP site. This feature allows you to put your data under the appropriate beamline as an anonymous user. Files are automatically deleted after 72 hours.

Putting files on the site while you're at BNL:

1. FTP ftp.nsls-user.bnl.gov
2. For user enter: anonymous for password enter: your e-mail.
3. cd to the beamline directory in the outbound dir and put your data directly there.
We recommend you compress your files and tar your directories.

Getting files from the site when you're at home:

1. FTP ftp.nsls-user.bnl.gov
2. For user enter : anonymous
3. For password enter: your email
4. At the FTP prompt, cd to the beamline directory in the outbound dir
5. Get your files

Backup to Laptop Computer

Archiving your data to your own Laptop Computer is the most recommended way. Users who only need access to the Internet on a short term or intermittent basis while working on the experimental floor at NSLS do not need a static IP address.The DHCP server on the network can be used to automatically assign an IP address to your computer. Follow the instructions for using DHCP on the following operating systems: Windows NT, Windows 98, Mac OS, Redhat Linux, Debian Linux, and other Linux.

Taking Backup on the DVD Media

Users will be able to backup their data presently in /data2 and /data3.

Below are step-by-step instructions on how to use k3b to write user-specified directories to a DVD media.

• You can start k3b by typing: k3b & on the command line or directly selecting the program from the Start Icon -> System -> Archiving ->k3b.
• Click on New Data DVD Project

• In the top window go to the directory where your data is being kept. If the data is stored in another system, please use scp command to transfer the data to the local hard disk or if the other hard disk is mounted, you can diectly access the data without having to transfer the data.

• Drag and drop the directories that need to be backed up on DVD media to the new DVD project.

• The burning device is the name of the DVD burner. In the options, select On the fly. You can select Verify Written Data if you want to check if the data written to your DVD media is correct (generally this option is not necessary).
• Now, click on the Burn to start the writing process.

USB and Firewire

USB and firewire connections as well as power cable that fits most of the external hard drives are provided and are located on the left corner of the desk, behind pro LCD display.

This is certainly the safest and fastest way to backup data, as long as hard drives are not NTFS formated.

Backup the data using cys on your external hard drive

 1. in cys : mount /mnt/fire or mount /mnt/fire2
 2. make a directory in the hard drive : mkdir /mnt/fire/x6aXXX
 3. cp -ar /data_val/User/Life#/date /mnt/fire/x6aXXX/
 4. and go for a LONG COFFEE: 
 5. when the data is backed up: umount /mnt/fire or /mnt/fire2

Taking Backup Using USB2.0

3 options are available.

Option 1: via the provided cable in HIS

    1. in his : the disk is automounted in the desktop
    2. Just drag your files or folder in the disk drive 
    3. make sure to unmount the drive after backup completed

Option 2: The lightest and most affordable.

    1. Bring internal hard drive (SATA or IDE) with no case and no power supply.
    2. Plug it on the available converter (see picture)
    3. Mount the drive
