Archiving

Project Archiving using tar

  1. Use the command tar to compress (gzip) the hpcLaunch folder on UCloud
  2. Check the size of the folder and compare it to the uncompress version. Use the du command (disk usage)
  3. Without unpacking the file, print the “table of contents”
  4. Unpack and save it to a new directory day1-copy
  5. Transfer the compress folder locally and calculate the resources in time (rsync --progress).
  6. Now, do the same for the uncompress version
# 1. Tar and compress 
tar  tar -czvf hpcLaunch.tar.gz hpcLaunch
# 2. Size comparison 
du -sh hpcLaunch
du -sh hpcLaunch.tar.gz
# 3.  Use the -t flag, for the file specified with the -f flag followed by the filename
tar –ftz mytarfile.tar 
# 4. Unpack into new dir
mkdir -p day1-copy
tar -xzvf hpcLaunch.tar -C day1-copy
# Transfer the compressed and uncompress folder using rsync (locally)
rsync -aP -e "ssh -i ~/.ssh/id_rsa -p <port>" ucloud@ssh.cloud.sdu.dk:/work/hpcLaunch PATH_LOCAL
