CopyToTape is a script for copying a folder from NorStore's disk area to NorStore's tape resource.

Run CopyToTape -h to print detailed instructions:

Usage: CopyToTape <path on disk> <path on tape> [none|gzip|bzip2]
 
Example: CopyToTape /projects/NS2345K/hirlam_nobackup /tape/NS2345K/hirlam 
 
Purpose: Copies a folder from disk to tape. 

Description: <path on disk> must be the absolute path to the input folder. 
              
             The output folder <path on tape> will be created - with parent  
             directories if necessary - and must not exist before running this 
             script. 

             The input data is staged in form of tar-chuncks in 
             /scratch/ingo/copytotape. The tar-chunks are removed from scratch 
             after success transfer to tape. 

             The size of a single tar-chunk is about 15Gb if no compression is 
             applied. If compression is applied, the size of the tar-chunks can 
             be up to 60Gb as a compression factor 4 is assumed.  

             Checksums for all input files are computed and stored in a separate 
             checksum file. The checksums are used to verify the tar-chunks.
