|

Specify the compression algorithm used for the checkpoint archive created

with the **--export, -e** option. Possible algorithms are *gzip*, *none*
|
||||
and *zstd*. If no compression algorithm is specified Podman will use

*zstd*.
|
||||
|
||||
One possible reason to use *none* is to enable faster creation of checkpoint
|
||||
archives. Not compressing the checkpoint archive can result in faster checkpoint
|
||||
archive creation.

# podman container checkpoint -l --compress=none --export=dump.tar
