Backup Data from Scratch Directories
This is done simply by copying data from the /nobackup/$USER directories to your home directory on Lou (lfe). The /nobackup/$USER directories are mounted onto lfe, so transfers should be done on lfe.
This can be done with scp, but is recommended to use NASA's in-house utility shiftc. shiftc will automatically perform parallel file transfers, data integrity checks and repairs, and syncing features similar to rsync.
Commands:
jrwrigh7@lfe7: shiftc -r -d --sync /nobackup/jrwrigh7/models/STGFlatPlate/STFM_Tet_dz4-10_dx15 .
This will copy the directory STFM_Tet_dz4-10_dx15 to the current location. The flags do as follows
-
-r: Recursively copy files from destination -
-d: Create required directories that don't already exist. Equivalent of the-pflag formkdir -
--sync: Only copy over "new" files, where "new" are any changes to the modification time or file size.
Once this command is submitted, the transfer process will be backgrounded. Progress can be viewed by running shiftc --monitor. Additionally, you will recieve an email with the transfer job is completed.
More documentation for shiftc can be found in its man page (man shiftc) and on NAS's documentation website.
