Status Quo Wipu

Podman Essentials

podman run --name mongo -v /home/fw/Devel/mongo/db:/data/db -v /home/fw/Devel/mongo/backup:/data/backup  -p 27017:27017 -d 336f61db

podman exec -it mongo bash

Mongo Essentials

Again I lost valuable lifetime because of mongorestore

root@eb5cf392f6bf:/data# mongorestore --verbose --drop --stopOnError --objcheck --dryRun --nsInclude=wipu.* backup/

• we need to assume sub-directories in the backup directory
• we need to give --verbose to see that the dry-run would work

Rustbelt

As we're starting from zero here it also does not matter what to note here
