Would be great if you can specify this in the title.
Doing one dump per table with chunking (each file has N rows) would help with both speed and disk sizes of backups by allowing S3 or some other program to implement de-duplication between incremental backups.
It also wouldn't hurt to capture the binlog position, if available, to enable point in time recovery.
Have a look at mydumper for an idea of how another tool implemented these:
Unfortunately embassies do care about these. Getting a work permit to immigrate to another country without an university degree certainly reduces the chances to get the embassy's approval, even in countries like Germany where there is some flexibility — if you have a Senior profile — a degree certainly accelerates the process.
In fact, in this industry, there is less people caring about an university degree than people who care about it, exceptions being those in the research field. But HR departments always filter out good candidates because they lack the degree, most HR employees are not trained correctly and/or know how difficult it is to hire a foreigner without a formal education background so they immediately throw good resumes to the trash can because of that.
If you have no degree, you just need to prove that you have sufficient skills or work experience. It's more paperwork for the company, but for them it's usually worth it.
If you want more info, I can ask the team who looks after it.
