Normally, there are no heading levels assigned to certain characters as the structure is
|
||
determined from the succession of headings. However, this convention is used in Python’s
|
||
Style Guide for documenting which you may follow:
|
||
|
||
# with overline, for parts
|
||
* for chapters
|
||
= for sections
|
||
- for subsections
|
||
^ for subsubsections
|
||
" for paragraphs

Listing all snapshots
|
||
=====================
|
||
|
||
Now, you can list all the snapshots stored in the repository:
|
||
|
||
.. code-block:: console
|
||
|
||
$ restic -r /tmp/backup snapshots
|
||
enter password for repository:
|
||
ID Date Host Tags Directory

|
||
9f0bc19e 2015-05-08 21:46:11 luigi /srv
|
||
|
||
You can filter the listing by directory path:
|
||
|
||
.. code-block:: console
|
||
|
||
$ restic -r /tmp/backup snapshots --path="/srv"
|
||
enter password for repository:
|
||
ID Date Host Tags Directory
|
||
----------------------------------------------------------------------
|
||
590c8fc8 2015-05-08 21:47:38 kazik /srv
|
||
9f0bc19e 2015-05-08 21:46:11 luigi /srv
|
||
|
||
Or filter by host:
|
||
|
||
.. code-block:: console
|
||
|
||
$ restic -r /tmp/backup snapshots --host luigi
|
||
enter password for repository:
|
||
ID Date Host Tags Directory
|
||
----------------------------------------------------------------------
|
||
bdbd3439 2015-05-08 21:45:17 luigi /home/art
|
||
9f0bc19e 2015-05-08 21:46:11 luigi /srv
|
||
|
||
Combining filters is also possible.

||
Checking a repo's integrity and consistency
|
||
===========================================
|
||
|
||
Imagine your repository is saved on a server that has a faulty hard
|
||
drive, or even worse, attackers get privileged access and modify your
|
||
backup with the intention to make you restore malicious data:
|
||
|
||
.. code-block:: console
|
||
|
||
$ sudo echo "boom" >> backup/index/d795ffa99a8ab8f8e42cec1f814df4e48b8f49129360fb57613df93739faee97
|
||
|
||
In order to detect these things, it is a good idea to regularly use the
|
||
``check`` command to test whether everything is alright, your precious
|
||
backup data is consistent and the integrity is unharmed:
|
||
|
||
.. code-block:: console
|
||
|
||
$ restic -r /tmp/backup check
|
||
Load indexes
|
||
ciphertext verification failed
|
||
|
||
Trying to restore a snapshot which has been modified as shown above will
|
||
yield the same error:
|
||
|
||
.. code-block:: console
|
||
|
||
$ restic -r /tmp/backup restore 79766175 --target /tmp/restore-work
|
||
Load indexes
|
||
ciphertext verification failed
|
||
|
||
By default, ``check`` command does not check that repository data files
|
||
are unmodified. Use ``--read-data`` parameter to check all repository
|
||
data files:
|
||
|
||
.. code-block:: console
|
||
|
||
$ restic -r /tmp/backup check --read-data
|
||
load indexes
|
||
check all packs
|
||
check snapshots, trees and blobs
|
||
read all data
|
||
|
||
Use ``--read-data-subset=n/t`` parameter to check subset of repository data
|
||
files. The parameter takes two values, ``n`` and ``t``. All repository data
|
||
files are logically devided in ``t`` roughly equal groups and only files that
|
||
belong to the group number ``n`` are checked. For example, the following
|
||
commands check all repository data files over 5 separate invocations:
|
||
|
||
.. code-block:: console
|
||
|
||
$ restic -r /tmp/backup check --read-data-subset=1/5
|
||
$ restic -r /tmp/backup check --read-data-subset=2/5
|
||
$ restic -r /tmp/backup check --read-data-subset=3/5
|
||
$ restic -r /tmp/backup check --read-data-subset=4/5
|
||
$ restic -r /tmp/backup check --read-data-subset=5/5
|
