What is partial backup in SQL Server
A partial backup resembles a full database backup, but a partial backup does not contain all the filegroups. Instead, for a read-write database, a partial backup contains the data in the primary filegroup, every read-write filegroup, and, optionally, one or more read-only files.

What is the best storage type for backup
Solid state drive (SSD) & flash drive (aka thumb drive, USB drive/stick) Flash drives and SSDs are the most efficient physical way to backup your system. Flash drives and solid state drives use flash technology to write and read data very quickly, making for speedy backups.
What is partial and full backup
A partial backup resembles a full database backup, but a partial backup does not contain all the filegroups. Instead, for a read-write database, a partial backup contains the data in the primary filegroup, every read-write filegroup, and, optionally, one or more read-only files.

Simple recovery model
This model automatically removes the transaction log records on every completed transaction. So, it doesn't support transaction log backups, only full or differential backup. If there is a malfunction or crash in the database, then you can restore it with the recent full or differential backup.
What is 4 3 2 backup strategy
Another relatively new option is 4-3-2. In this case, four copies of the data are stored in three locations, but two of these must be off-site. The 4-3-2 strategy means that backups are duplicated and geographically distant from one another to protect against natural disasters.
