LTS ([long term storage](https://ethz.ch/services/en/it-services/catalogue/storage/lts.html)) is a tape long-term archival system run by Informatikdienste. If you have *cold* data (not in active use any longer) that should still be kept around but will likely not be accessed for years to come, LTS is for you. In a nutshell, it works like this:
- you collect the data in a specific folder on the file server
- we then use a bunch of scripts around the [dar](http://dar.linux.free.fr/) archiver to create a set of 200G archive files that we then write onto the LTS ingress share
- LTS then duplicates the archive to a second tape robot so there are always two copies
- when this copy process has finished, you'll be able to verify your archive on our [LTS dashboard](https://ltsdash.phys.ethz.ch/)
- once you/we have made sure the data has been committed to LTS, we can delete the files from the file server
