out of memory when restoring

```
[root@localhost:~] /opt/ghettovcb/bin/ghettoVCB-restore.sh -c /vmfs/volumes/datastore_m2/Debian-2024-2024-06-25_02-20-00   -d 1
sh: out of memory


```

I tried restoring compressed file (.gz), I tried uncompressing the file and then restoring

Why would I get out of memory?
