The HSM system ist shared/exported/mounted read only. To write data into the tape archive use one of the following options:
| Suggestion | Command | Important Notes |
|---|---|---|
 Best choice | rsync -e ssh -Pauv <file|dir> <username>@hssrv2.dmawi.de:<destination-dir> | rsync is the most versatile way way of transfering transferring data. E.g., it allows updates with the -u option. This ensures that only new files are copied (and overwritten), existing (unchanged) files are not touched. This is important to reduce avoid tape accesswaste. When copying directories you need -r (recursive, already included in -a). |
| Fast choice | sftp filezilla | sftp providesfastway of transferring large amounts of data. Use your favorite ftp-client. However, note, that only two connections per user (per HSM server) are allowed. If you request more, your connection will terminate. sftp uses the secure ssh-protocol and should be preferred. Use port 22 for sftp. |
 Do not use! | scp <file|dir> <username>@hssrv2.dmawi.de:<destination-dir> | scp seems convenient, but it is slightly slower when transferring data compared to ftp and/or rsync. It also just overrides existing files and no update (like rsync -u) is possible. This would also create new tape copies, you do not want to do that!!! |
