The example given for the format of an index shows a mixed pack file.
Mixing tree and data blobs has been deprecated for a long time. Thus,
change the pack to only contain "data" blobs.
The output is now
```
-v, --verbose be verbose (specify multiple times or a level using --verbose=n, max level/times is 2)
```
instead of
```
-v, --verbose n be verbose (specify multiple times or a level using --verbose=n, max level/times is 2)
```
The maximum for `--verbose=n` is n=2. Internally it is translated into a
scale from 0 to 3. However, the default (without verbose) is 1, thus the
verbosity level can only be increased two times.
The scanner process has only cosmetic effect for the progress printer,
and can be disabled without impacting functionality when the user does
not need an estimate of completion.
In many cases the scanner process can provide beneficial priming of
the file system cache, so as general advice it should not be disabled.
However, tests have shown that backup of NFS and fuse based filesystems,
where stat(2) is relatively expensive, can be significantly faster
without the scanner.
There is no need to use a special wildcard `**` to demonstrate negative
patterns. Actually, it is both slower than the simpler variant and seems
to confuse users.
`init` and `copy` use `--repo2` with two different meaning which has
proven to be confusing for users. `--from-repo` now consistently marks a
source repository from which data is read. `--repo` is now always the
target/destination repository.
It wasn't clear that Google Cloud Storage and Google Drive are two different services and that one should use the rclone backend for the latter. This commit adds a note with this information.
If no specific Region is mentioned in RESTIC_REPOSITORY, AWS defaults to
us-east-1. For this reason, users that follow the tutorial and create
their S3 bucket in any other region get the following error:
"Fatal: create repository at [...] client.BucketExists"
Explicitly specifying the AWS region name fixes the issue.
The new option allows prune to operate with nearly no scratch space by only removing
no longer necessary pack files and first deleting the index before
rebuilding it. By first deleting the index it becomes safe to just
delete no longer necessary pack files. However, as a downside there's
now the risk that the repository becomes inaccessible if prune fails.
To recover from that problem a user might have to manually delete the
repository index and then run (a full) `rebuild-index` again.
Removing data based on a policy when the attacker had the opportunity to
add data to your repository comes with some considerations. This is
added to the 060_forget.rst documentation.
That document is also updated to reflect that restic now considers
the current system time while running "forget".
References to the security considerations section are added:
- In `restic forget --help`
- In the threat model (design.rst)
- In the (030) setup section where an append-only setup is referenced
A reference is also to be added to the `rest-server` readme's
append-only paragraph (see my fork).
This commit also resolves a typo (amount->number for countable noun),
changes a password length recommendation into the metric that
actually matters when creating passwords (entropy) since I was editing
these doc files anyway, and updates the outdated copyright year in
`conf.py`.
Some wording in 060_forget (line 21..22) was changed to clarify what
"forget" and "prune" do, to try and avoid the apparent misconception
that "forget" does not remove any data.
This is quite similar to gitignore. If a pattern is suffixed by an
exclamation mark and match a file that was previously matched by a
regular pattern, the match is cancelled. Notably, this can be used
with `--exclude-file` to cancel the exclusion of some files.
Like for gitignore, once a directory is excluded, it is not possible
to include files inside the directory. For example, a user wanting to
only keep `*.c` in some directory should not use:
~/work
!~/work/*.c
But:
~/work/*
!~/work/*.c
I didn't write documentation or changelog entry. I would like to get
feedback if this is the right approach for excluding/including files
at will for backups. I use something like this as an exclude file to
backup my home:
$HOME/**/*
!$HOME/Documents
!$HOME/code
!$HOME/.emacs.d
!$HOME/games
# [...]
node_modules
*~
*.o
*.lo
*.pyc
# [...]
$HOME/code/linux/*
!$HOME/code/linux/.git
# [...]
There are some limitations for this change:
- Patterns are not mixed accross methods: patterns from file are
handled first and if a file is excluded with this method, it's not
possible to reinclude it with `--exclude !something`.
- Patterns starting with `!` are now interpreted as a negative
pattern. I don't think anyone was relying on that.
- The whole list of patterns is walked for each match. We may
optimize later by exiting early if we know no pattern is starting
with `!`.
Fix#233
The keyfile provided by restic's own webserver (https://restic.net) should be
more stable than relying on public keyservers. So I changed the URL to the
GPG keyfile, as recommended by MichaelEischer.
Per Amazon's product page [1], S3 is officially called "Amazon S3". The
restic project uses the phrase "AWS S3" in some places. This patch
corrects the product name.

Dependencies are fetched at build time and stored in the GOPATH. These paths end up being in the final binary.
Bump restic version to latest and go version to the 1.16.6, which was used to build restic 0.12.1.
This can be used to check how large a backup is or validate exclusions.
It does not actually write any data to the underlying backend. This is
implemented as a simple overlay backend that accepts writes without
forwarding them, passes through reads, and generally does the minimal
necessary to pretend that progress is actually happening.
