Hi,

I treat my internal SSDs in the same way I treated internal HDDs,
excepted of periodic TRIM and got the impression that SSDs suffer less
from wear than HDDs do.

You could kill two birds with one stone by making a backup e.g. by
using tar with compression to shrink the size and then restoring from
that backup.

  tar --xattrs -czf

you could replace the "z" option by any other compression.

You could make a fast copy by running

  cp -ai

for the cp command you don't need to add the "i", however add
"--xattrs" to tar and use the "-a" flag for cp.

Yes, you can.
