24. Snapshot
A Snapshot is a view of a data set frozen at a point in time which allows
applications to continue writing their data.
Bacula offers snapshot support across
a wide range of operating systems and environments,
including of course Windows,
Unix and
Linux platforms.
The following snapshot-capable file systems and
logical volume managers are now supported with
Bacula Enterprise 8.2
ZFS
BTRFS
LVM
25. CDP
Continuous Data Protection (CDP) also called continuous backup or real-time backup,
refers to backup of Client data by automatically saving a copy of every change made
to that data,
essentially capturing every version of the data that the user saves.
●
Transaction record preservation, where corrupt files are replaced with earlier and clean versions
●
Efficient data recovery
●
Easy installation and programming, which does not affect stored data
26. CDP
The user application (cdp-client or tray-monitor) is responsible to monitor files and directories.
When a modification is detected, a copy of the new data is done into a spool directory.
At a regular interval, a Bacula backup job will contact the FileDaemon and will save
all the files archived by the cdp-client.
The local data can be restored at any time without a network connection to the Director.
