Hi @akandis,
Is your deployed solution managed or unmanaged? If it is managed, you have the ability to uninstall the solution. However, do be aware that data loss will occur for any new tables or new columns to an existing table when you uninstall the solution they were introduced in.
If the solution is unmanaged, unfortunately you will have to remove each component manually. Note that the same data loss scenario applies when deleting any tables or columns.
The other option, and as a general best practice, is to take a backup of the environment prior to the deployment of a solution. If the deployment goes unsuccessful and requires a rollback, you can simply restore the database. Note that all data and customizations added after the backup was taken will be lost after a restore, so you'll want to ensure sufficient smoke testing occurs so that any rollback decision can be made before users are let back into the system and begin entering business data again.
You can review the following references for more details.
