PACKAGE := dss
-SLOGAN := the dyadic snapshot scheduler
-define DESCRIPTION1 :=
- $(PACKAGE) maintains hardlink-based snapshots of a given directory on a
- remote or local host using rsync's link-dest feature. The snapshots
- are organized so that any snapshot can directly be deployed as an
- (emergency) replacement for the primary system.
-endef
-define DESCRIPTION2 :=
- $(PACKAGE) is admin friendly: It is easy to configure and needs little
- attention after the initial setup. In particular, no full, incremental
- or differential backups need to be configured, and there is no database
- to maintain. $(PACKAGE) is also user-friendly: Assuming the snapshot server
- allows read-only user access over the network, users can restore
- accidentically removed files without admin intervention, using their
- favorite file browser to copy files from the snapshot directory back
- to the primary system.
-endef
-define DESCRIPTION3 :=
- $(PACKAGE) keeps track of the age and the state of existing snapshots and
- triggers snapshot creation and removal according to the configuration
- settings. It tries to maintain a scheme where many recent snapshots
- and few old snapshots exist, for example 16 snapshots newer than a
- week, 8 snapshots between one and two weeks old, 4 snapshots between
- two and three weeks old, and so on.
