Multi Database
To backup a whole database provide the option --multi-database
.
For example: bouch backup http://localhost:5984
Filtering
To filter the processed databases use the --filter
option, where you can provide a minimatch pattern.
Only works for backup
and migrate
.
For example: bouch backup http://localhost:5984 --multi-database --filter 'prefix-*'
Renaming
To rename the restored databases use the --rename
option, where you can provide a JS code to manipulate the target database names.
Only works for restore
and migrate
.
Examples:
$ bouch migrate http://localhost:5984 --multi-database --filter 'prefix-*' --rename 'name.replace(/^prefix-/, "prefix2-")'
or use a file to define the renaming script.
// content of renaming.js
const map = {
foo: 'bar',
baz: 'foobar'
}
const arr = name.split(/-/);
arr[0] = map[arr[0]];
return arr.join('-')
$ bouch migrate http://localhost:5984 --multi-database --filter '(foo|bar)-*' --rename @renaming.js
