 * This utility simplifies the volume backup process.
 * ```ts
 * export const { createBackup, restoreBackup } = Backups.volumes("main").build();
 * ```
 *
 * Changing the options of the rsync, (ie exludes) use either
 * ```ts
 *  Backups.volumes("main").set_options({exclude: ['bigdata/']}).volumes('excludedVolume').build()
 * // or
 *  Backups.with_options({exclude: ['bigdata/']}).volumes('excludedVolume').build()
 * ```
 *
 * Using the more fine control, using the addSets for more control
 * ```ts
 * Backups.addSets({
 * srcVolume: 'main', srcPath:'smallData/', dstPath: 'main/smallData/', dstVolume: : Backups.BACKUP
 * }, {
 * srcVolume: 'main', srcPath:'bigData/', dstPath: 'main/bigData/', dstVolume: : Backups.BACKUP, options: {exclude:['bigData/excludeThis']}}
 * ).build()
 * ```
