test.txt.20150321200204.tbz  test.txt.current.tbz

# item.archives does not contain current-archive.

# item does not restore if it has no change.
In [16]: item.restore()
In [17]: !ls savedir/
test.txt.20150321200204.tbz  test.txt.current.tbz

In [18]: !rm savedir/test.txt.current.tbz
# if specified refuge_current "false", current-archive does not save.
In [19]: item.restore(force=True, refuge_current=False)
In [20]: !ls savedir/

Rotation Example

This is a sample to delete from the oldest archive.

In [1]: import bak
In [2]: item = bak.Item('test.txt', 'savedir')

# add handler by item.on, specify Signal and Behavior set.
# FillSignal: archive number reaches value specified, execute behavior.
# RemoveBehavior: remove specified index(es) of archive(s).
In [3]: item.on(bak.FillSignal(3), bak.RemoveBehavior(-1))
Out[3]: <test.txt (0)>

In [4]: item.archives
Out[4]: []

In [5]: item.save(force=True)
In [6]: item.archives
Out[6]: ['test.txt.20150321204308.tbz']

In [7]: item.save(force=True)
In [8]: item.archives
Out[8]: ['test.txt.20150321204313.tbz', 'test.txt.20150321204308.tbz']
