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. Change history: 2014.04.16 first version of CopyToTape
