Data from /home and /lustre can be moved into long term tape archives located at the FHI in Berlin.
Backup/Archiving is handled most conveniently via a CLI installed on the machine
How to use the archive/backup client
There is a command line client for this called dsmc. If you do not want to keep the GUI open for longer periods while creating a larger archive you can use this to create archives.
The syntax is simply:
dsmc archive <-subdir=yes> /directory/
To archive files or whole directories. To include subdirs the
Listing archived data:
You can display a list of the files you have archived from the current directory using
dsmc query archive ‘*’
Note that the archive system remembers the directory that the file was archived from, and by default will restore it to the same place (see later). When you do the query command, you have to either be in the right directory, or give the path to the original directory. You can also list all the files archived under a given directory, for example
dsmc query archive -subdir=yes ‘/lustre/AEI/<username>/*’
Retrieve archived data:
You can retrieve archived data and subdirectories by using the command
dsmc retrieve -subdir=yes /lustre/PATH/ Backup
Backup is taken of the /home area only. An incremental backup is taken every night. Please mark that there are no backup of files stored on the work areas.
In our institute the backup data will be stored for 90 days and there is no limit concerning the number of versions which are stored. The archiving data is stored indefinitely.
Exclude directories from being backed up:
No backups are taken from files within the NOBACKUP directories in /home/username wherever they are located.
