### Add Todays date in a groff document.
	Sat Dec 17 04:07:17 PM UTC 2022
Groff has some built-in Registers.
For the date it has:
```
	\n[dw] Day of the week(1-7)
	\n[dy] Day of the Month(1-31)
	\n[mo] Current Month(1-12)
	\n[yr] The Current Year minus 1900 (old version)
	\n[year] The Current Year. (new version)
```
For Time is has the built-in registers:
These get initialized at start-up of groff
```
	\n[seconds] 0-59
	\n[minutes] 0-59
	\n[hours] 0-23
```
So to display date in iso style: 
> \n[year]-\n(mo-\n(dy

### Backup your server mariadb database to local computer
	Fri Mar 19 21:43:17 UTC 2021
```
ssh -C host mysqldump yourdatabase > yourdatabase.sql && gzip yourdatabase.sql
```

The -C in ssh is for compression which saves a lot of time over slower internet connections.
The redirect symbol(">") sents the screen output from the remote machine to the local machine into a file yourdatabase.sql
After succes,thats what the double && are for, gzip database for storage.

### Restore your servers mariadb database

copy your backup file to the server
e.g. with scp, rsync ...

```
scp yourdatabase.sql.gz yourserver:/tmp/
ssh yourserver
cd /tmp
gunzip yourdatabase.sql.gz ; mysql yourdatabase < yourdatabase.sql
```
