Description
|
|
~~~~~~~~~~~
|
|
|
|
Analyze archives to find "hot spots".
|
|
|
|
Borg analyze relies on the usual archive matching options to select the
|
|
archives that should be considered for analysis (e.g. ``-a series_name``).
|
|
Then it iterates over all matching archives, over all contained files and
|
|
collects information about chunks stored in all directories it encountered.
|
|
|
|
It considers chunk IDs and their plaintext sizes (we don't have the compressed
|
|
size in the repository easily available) and adds up added/removed chunks'
|
|
sizes per direct parent directory and outputs a list of "directory: size".
|
|
|
|
You can use that list to find directories with a lot of "activity" - maybe
|
|
some of these are temporary or cache directories you did forget to exclude.
|
|
|
|
To not have these unwanted directories in your backups, you could carefully
|
|
exclude these in ``borg create`` (for future backups) or use ``borg recreate``
|
|
to re-create existing archives without these. |
