The above command will dump all
databases except for test and unimportant_db from server.com
The data from two tables, large_table1 & cachetable,
(found in database largedb) will be ignored, however the table structure will be
backed up. This is especially handy if you have temporary tables or large
tables which contain unimportant / cached data.
A total of 30-days of backups
will be kept. Note: Backups are named by date
(yyyy-mm-dd.tar.xz), so a maximum of 1 backup per day can be kept. If the
script is re-run on the same day, the repository is synced and the existing
daily backup overwritten.
