- 2025-01-14 11:10 Extension to availability of `/old_lustre` on Young until **9am on Tues 28 Jan**

We've had multiple requests from people who have been unable to retrieve their data from Young's
old_lustre in time for the removal of the filesystem today, so we are extending the deadline for
two weeks.

The old filesystem on Young will be unmounted shortly after **9am on Tuesday 28 January**.

There have been some questions about ways to transfer files in chunks if your transfers are being
interrupted, without repeating copying the same files - you can use `rsync` for this as it can
resume incomplete copies by running again, and if you use the `-a` option ("archive") it retains
many of the file properties, including e.g. timestamps.

> Use archive mode (recursively copy directories, copy symlinks without resolving, and preserve
> permissions, ownership and modification times):
>
> `rsync -a|--archive path/to/source path/to/destination`
(This shows that you can use `-a` or `--archive` as the option passed in).

Alejandro Santana-Bonilla (KCL) also created a script for copying your first 10 (or other number)
directories, then second 10 and so on, if that is useful to you:
