About Trimming Algorithms
SonicWALL CDP offers two trimming algorithms:
•
Delete Oldest
•
Decay
If you are using the Decay option, it will work as described in the following example. As a
hypothetical, assume you have backed up a file once per day for a year. After one year of Decay
mode trimming, the final end result of revisions may look like this:
•
1 revision from a year ago
•
1 revision from 6 months ago
•
2 revisions from 3 months ago
•
3 revisions from this month
The Decay mode uses internal logic that attempts to give a broad range of revisions over time,
with an emphasis on more recent revisions. This was the standard behavior used in SonicWALL
CDP versions 3 through 5.0.
The Delete Oldest algorithm is linear (the same as application trimming in CDP 5.x). If you
configure it to save 5 revisions and the 6th comes in, the oldest revision chronologically
recorded will always be the one that is deleted.
