CopyToTape

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.
