To internal discs

For quickly transfer your observational data to an internal data reduction area, please use rsync following these examples:

Issue again rsync every time you need to update your data at the destination directory with the most recent runs acquired. See also transferring data to FTP areas.

The following are data areas at the disposal of the visitors:

Directory	Assigment	Comments
/scratch/whta/	WHT observers	Scratch area. No backups.
/obsdata/whta/	WHT observers	WHT observational data. Do not edit (create, modify or remove) any data in this directory.
/obsdata/outgoing/whtguest/	WHT observers	FTP area anonymously acccesible at ftp://ftp.ing.iac.es/whtguest/. Do not reduce data here.
/data/whtguest/	WHT observers	whtguest data repository.
/data/weaveql_nfs	Synology disk on the mountain whtnfs1	WEAVE QL data as processed by the s/w on WEAVEQL PC (see https://ingjira.ing.iac.es:8443/browse/WEAVEWSF-34)
/scratch/inta/	INT observers	Scratch area. No backups.
/obsdata/inta/	INT observers	INT observational data. Do not edit (create, modify or remove) any data in this directory.
/obsdata/outgoing/intguest/	INT observers	FTP area anonymously accesible at ftp://ftp.ing.iac.es/intguest/. Do not reduce data here.
/data/intguest/	INT observers	intguest data repository.
/scratch/slo/	SLO users	Scratch area. No backups.
/obsdata/outgoing/sloguest/	SLO guests	FTP area anonymously acccesible at ftp://ftp.ing.iac.es/sloguest/. Do not reduce data here.
/data/sloguest/	SLO guests	Data area for sloguest user.

To external storage devices

All our public computers provide USB 2.0 and FireWire IEEE 1394 ports to which you can plug your external hard disc or flash memory. Plug your device and this will be automatically mounted on a directory under /media. Once recorded, unmount the device (select 'eject' on the device icon), wait and unplug.

To DVDs

All our public computers can record DVDs. Please ask your Support Astronomer or Telescope Operator for a blank DVD. At ING we supply DVD-R discs as default, which have a total capacity of 4.7GB. You can either record your data using K3b application or from the command line:

Using K3b application:

As a default, the systems asks you what to do when you insert a blank DVD in the DVD writer.

Select "Create Data DVD with K3b" and click on OK. This will start K3b. If it doesn't start, then type "k3b" at the prompt of your terminal window, for instance, for intguest on INTDRPC1:

intguest@intdrpc1>k3b &

Once K3b starts, then you can select what data to record. At the top, enter the directory path of your files, for instance, "/obsdata/whta/20081201/" and you will see below the files in there. Then select the files that you want to save (press CTRL+A to select all) and drag the files to the window to the right below. If you can see that window but instead you are shown different options, click on the option "New Data DVD Project" and you will see the selected files window:

When done, press the "Burn" buttom to the left of the burning window. You will see a window with the different burning options.

The default options are good enough, but if you wish you can modify them. Click on "Burn" to start recording:

When finished, you could see a new window that opens because the system detects the already recorded disc. You can select between opening and checking that everything is there, or do nothing:

Close the burning window, exit K3b and save or discard the configuration of your recording:

From the command line:

In the directory where the files are located, type:

growisofs -Z /dev/dvdrw -R -J *

Please note that, depending on which PC you are logged on, the name of the DVD recording device might be different from /dev/dvdrw (ie. /dev/dvdrw1). Please see the available DVD devices by listing the directory /dev/dvd*.

The command growisofs offers more options, to see the manual, type:

man growisofs

To laptops on ingext network

Data can be transferred directly to your laptop over the ingext network. This can be done file by file using the scp command on your laptop, for example, for transferring INT data: :

The * can always be used as a wildcard. For WHT data, replace intguest@intdrpc1 by whtguest@whtdrpc1, and specify a valid directory path.

Alternatively the rsync command can be used to copy all the files from a directory to your laptop. Running the command another time then updates your laptop's directory only with the new data, for example:

rsync -auv intguest@intdrpc1:/obsdata/inta/yyyymmdd /your/directory

To FTP areas

Data can be copied to the ING ftp area /obsdata/outgoing/<username>/, where <username> is an ING username. In the case of visitors, <username> is the one provided by the Observing Support Astronomer upon arrival at the telescope. Delete the data on the ftp area once downloaded, or contact your Observing Support Astronomer to do it on your behalf. The following are some examples on how to copy the data from the observing directories to the ftp area:

If you need to transfer the data to the ftp area frequently, you can use rsync:

Use one of the methods above for downloading the data. When prompted for a username and password, enter whtguest or intguest and the password provided by your Observing Support Astronomer. Below are more examples:

sftp whtguest@ftp.ing.iac.es:whtguest/yyyymmdd
sftp> get -r *

sftp intguest@ftp.ing.iac.es:intguest/yyyymmdd
sftp> get -r *
