Operation Manual

NOTE: Limit and Age
NUMBER_LIMIT and NUMBER_MIN_AGE are always evaluated both.
Snapshots are only deleted when both conditions are met. If you always
want to keep a certain number of snapshots regardless of their age, set
NUMBER_MIN_AGE to 0. On the other hand, if you do not want to keep
snapshots beyond a certain age, set NUMBER_LIMIT to 0.
NUMBER_LIMIT
Denes how many snapshots to keep if NUMBER_CLEANUP is set to yes.
NUMBER_MIN_AGE
Denes the minimum age in seconds a snapshot must have before it can automati-
cally be deleted.
TIMELINE_CREATE
If set to yes, hourly snapshots are created.This is currently the only way to auto-
matically create snapshots, therefore setting it to yes is strongly recommended.
Valid values: yes, no
TIMELINE_CLEANUP
Denes whether to automatically delete old snapshots when the snapshot count
exceeds a number specied with the TIMELINE_LIMIT_* options and an age
specied with TIMELINE_MIN_AGE. Valid values: yes, no
TIMELINE_MIN_AGE
Denes the minimum age in seconds a snapshot must have before it can automati-
cally be deleted.
TIMELINE_LIMIT_HOURLY, TIMELINE_LIMIT_DAILY,
TIMELINE_LIMIT_MONTHLY, TIMELINE_LIMIT_YEARLY
Number of snapshots to keep for hour, day, month, year.
