Install on GitLab instance or Install on Ubuntu?

[yohoho]

Yesterday (hasn't sleep; a startup; CEO act as an IT too to cut cost; no monitor today)
1. We lost 1.5 GB of company data due to "my idiocy"
2. I tried to delete a blank group in Nextcloud and it just wont.
3. I assume it because there's still a user.
4. I remove every user related to that group.
5. My account act as the owner of the company parent folder.
6. Gone 1.5 GB of file (most of them? Proof of Bill; -$8,000 approx in a day. PhotoRec did not help. Thousand of files. Neither Testdisk.

I've had enough of "error" and stuff. It waste my time. I am thinking to use GitLab instance so I can test it before put it on the production environment.

Is it a good idea?

How I will use GitLab instance?
1. To make things more neat based on project. /mail ; /cloud ; etc.
2. Backup based on version.
3. To test integration before release on production environment.

Or is it an overkill?
