Long story short, we had a hosting plan on www.hostforlife.eu (btw, terrible service even on more expensive packages, plus they lost ALL files on their servers and we had to restore our backups as they lost those too) and for db backups we were opening tickets so they would take them manually for us.
When we moved to another host (the plan with hostforlife had expired) and tried to restore the SQL Server 2014 backup we couldn't do it (our host actually).
The backup had no extension and we are not sure what type of backup it is (a couple of methods were tried but didn't work).
We contacted their support for this but because we had no active plan they refused to even tell us how the backup was taken.
We could pay for a 3 month hosting but I do not want to give any more money to this crappy company.
So, my question is, how can we identify the backup type to restore it?
