I needed to automate the dump process of my databases and searching on the internet I found a very interest list of commands we can use.

If you wanted daily database dumps to last for a week, you could run something like that:

$ mysqldump -uMY_USERNAME -p MY_PASSWORD MY_DATABASE | gzip > /some_path/db_backup/file_bkp_$( date +"%a" ).sql.gz

It would create a file with the name “file_bkp_Tue.sql.gz”.  Considering the fact you’re using the weekday variable, it would be replaced every 7 days in a cronjob.

Example of cronjob to run everyday at 1:10am with the database dump above:

10 1 * * *  mysqldump -uMY_USERNAME -p MY_PASSWORD MY_DATABASE | gzip > /some_path/db_backup/file_bkp_$( date +"%a" ).sql.gz

If your want to set any other parameters for your files names (e.g. file_bkp_$( date +”%Y_%m_%d” ).sql),  you can use, for instance, any of the values in the table below:

Specifier Description
%a Abbreviated weekday name (Sun..Sat)
%b Abbreviated month name (Jan..Dec)
%c Month, numeric (0..12)
%D Day of the month with English suffix (0th, 1st, 2nd, 3rd, …)
%d Day of the month, numeric (00..31)
%e Day of the month, numeric (0..31)
%f Microseconds (000000..999999)
%H Hour (00..23)
%h Hour (01..12)
%I Hour (01..12)
%i Minutes, numeric (00..59)
%j Day of year (001..366)
%k Hour (0..23)
%l Hour (1..12)
%M Month name (January..December)
%m Month, numeric (00..12)
%p AM or PM
%r Time, 12-hour (hh:mm:ss followed by AM or PM)
%S Seconds (00..59)
%s Seconds (00..59)
%T Time, 24-hour (hh:mm:ss)
%U Week (00..53), where Sunday is the first day of the week; WEEK() mode 0
%u Week (00..53), where Monday is the first day of the week; WEEK() mode 1
%V Week (01..53), where Sunday is the first day of the week; WEEK() mode 2; used with %X
%v Week (01..53), where Monday is the first day of the week; WEEK() mode 3; used with %x
%W Weekday name (Sunday..Saturday)
%w Day of the week (0=Sunday..6=Saturday)
%X Year for the week where Sunday is the first day of the week, numeric, four digits; used with %V
%x Year for the week, where Monday is the first day of the week, numeric, four digits; used with %v
