Why did I write the application ? When I read about Apple's
|
|
TimeMachine I thought it's nice tool to have. I searched for
|
|
equivalent applications for Linux and I find TimeVault and FlyBack.
|
|
I didn't feel very comfortable with TimeVault, especially with it's
|
|
time line. FlyBack was almost what I was looking for: I wanted a
|
|
Places/Bookmarks column and I wanted snapshots only when something
|
|
changed (just to reduce the number of snapshots).
|
|
|
|
Keep in mind that Back In Time is just a GUI. The real magic is
|
|
done by rsync (take snapshots and restore), diff (check if something
|
|
changed) and cp (make hard links).
|
|
|
|
Back In Time acts as a "user mode" backup system. This means that
|
|
you can backup/restore only folders you have write access to
|
|
(actually you can backup read-only folders, but you can't restore
|
|
them).
|
|
|
|
In order to reduce disk space, it use the following rules:
|
|
|
|
* a new snapshot is created only if the last snapshot (if any)
|
|
is different from the current directories state
|
|
* when a new snapshot is created, it use hard-links (if possible)
|
|
for files that are not modified
