No it cannot. It can do a scheduled periodic backup and be told to keep
n backups, essentially a retention scheme.
An incremental backup is when a full backup is taken and then only
changed data is backed up until the next full "image copy",
increments. In this way both the size and the duration of the backup is minimized at the expense of having to go back to the last full copy, restore that, then apply the incrementals forward to get back to currency. This
can, in some cases, also permit a "point-in-time" recovery in-between (or in the middle of) incrementals, thereby allowing for a restoration prior to some inadvertant application data corruption, independent of a full system recovery.
It is not uncommon to see the term incremental misused in this way, confused with rotation or retention schemes.
