Just wanted to make sure you're aware, tar support is built-into synchro.net since v3.19 I think.

Also, you don't need to change the cwd (cd command), that's usually a red flag/code smell:
 - tar (for Linux at least) has the `-C` option
```
       -C, --directory=DIR
              Change to DIR before performing any operations.  This option is order-sensitive, i.e. it affects all options that follow.
```
Also this option looks possibly relevant to your needs:
```
       --one-top-level[=DIR]
              Extract all files into DIR, or, if used without argument, into a subdirectory named by the base name of th
e archive (minus standard compression suffixes recognizable by --auto-compress).
```
