Backup

Local and cloud backups are two methods of copying your data to a location
different from the original source. The main difference between them is the
storage location of the backup data.

Local backup

involves copying data to physical storage
devices, such as a hard drive, disk drive, or
USB, located in the same places as the
source data. Local backups provide more
control and faster access to backup data
than cloud backups, but they also require
more maintenance and incur costs for
hardware and software. Local backups can
also be susceptible to theft, damage, or
disasters affecting your core data.

Cloud backup

involves copying data over the network to a
remote storage server, typically hosted by a
service provider (Google, OneDrive –
Microsoft, iCloud, etc.). Cloud backups save
you money and resources on hardware and
software, protect your data from local
disasters or cyber-attacks, and allow you to
access your data from anywhere with an
internet connection. However, cloud
backups may have drawbacks such as
slower performance and higher bandwidth consumption compared to local
backups.

Some organizations use a mixed approach, combining local and cloud backups to
balance the advantages and disadvantages of both methods.
