Packaging of folders before copying/moving/linking

[JanStreffing]

I recently started an AWI-CM3 production run on aleph without netcdf FESOM2 restarts. Only binary. Normally we move the binary restart files from the old to the new run folder at the end of a run. It's not viable to copy them out first, because it's too many files. (because time to copy is long and number of files goes towards file limit).

I tried a parallel packing like this: tar cf - np1280 | pigz -p 30 > archive.tar.gz. This was quite fast. We could then move this archive out and move the unpacked files to the new work folder.

How would this best be done? plugin script, modification of python backend?

This resulted in a new plugin that tars binary restart files for FESOM2.
