The well-known [datamover tools](../../data_transfer/datamover/) are available to run such transfer
jobs under Slurm. The steps are as follows:
1. Login to Barnard: `ssh login[1-4].barnard.tu-dresden.de`
1. The command `dtinfo` will provide you the mountpoints
```console
marie@barnard$ dtinfo

/data/old/lustre/ssd Taurus /lustre/ssd
[...]
```
1. Use the `dtls` command to list your files on the old home directory: `marie@barnard$ dtls
/data/old/home/marie`
1. Use `dtcp` command to invoke a transfer job, e.g.,
```console
marie@barnard$ dtcp --recursive /data/old/home/marie/<useful data> /home/marie/
```
**Note**, please adopt the source and target paths to your needs. All available options can be
queried via `dtinfo --help`.
!!! warning
Please be aware that there is **no synchronisation process** between your home directories at
Taurus and Barnard. Thus, with the very first transfer, they will become divergent.
We recommand to **take some minutes for planing the transfer process**. Do not act with
precipitation.
