To identify the mount points of the different filesystems on the data transfer machine, use
`dtinfo`
. It shows an output like this:

## How to copy your data from an old scratch (Atlas, Triton, Venus) to our new scratch (Taurus)
You can use our tool called Datamover to copy your data from A to B.
dtcp -r /scratch/<project or user>/<directory> /projects/<project or user>/<directory> # or
dtrsync -a /scratch/<project or user>/<directory> /lustre/ssd/<project or user>/<directory>
Options for dtrsync:
-a, --archive archive mode; equals -rlptgoD (no -H,-A,-X)
-r, --recursive recurse into directories
-l, --links copy symlinks as symlinks
-p, --perms preserve permissions
-t, --times preserve modification times
-g, --group preserve group
-o, --owner preserve owner (super-user only)
-D same as --devices --specials
Example:
dtcp -r /scratch/rotscher/results /luste/ssd/rotscher/ # or
new: dtrsync -a /scratch/rotscher/results /home/rotscher/results

## Examples on how to use data transfer commands:
Copying data from Taurus' /scratch to Taurus' /projects
% dtcp -r /scratch/jurenz/results/ /home/jurenz/
Moving data from Venus' /sratch to Taurus' /luste/ssd
Copying data from /beegfs/global0 to /projects filesystem.
% dtmv /scratch/jurenz/results/ /lustre/ssd/jurenz/results
```
console
marie@login$
dtcp
-r
/beegfs/global0/ws/marie-workdata/results /projects/p_marie/.
```
Moving data from /beegfs/global0 to /warm_archive filesystem.
TGZ data from Taurus' /scratch to the Archive
```
console
marie@login$
dtmv /beegfs/global0/ws/marie-workdata/results /warm_archive/ws/marie-archive/.

Please do not
generate files in the archive much larger that 500 GB.

!!! hint
!!! note
Please do not generate files in the /archiv filesystem much larger that 500 GB.
The [warm archive](../data_lifecycle/warm_archive.md)) is not writable from within batch jobs.
!!! note
The
[
warm archive
](
../data_lifecycle/warm_archive.md
)
and the projects filesystem are not writable from within batch jobs.
However, you can store the data in the warm archive with the datamover.
