+
+You can ask questions in our [Discourse forum](https://forum.restic.net).
+

+
+# Backends
+
+Saving a backup on the same machine is nice but not a real backup strategy.
+Therefore, restic supports the following backends for storing backups natively:
+
+- [Local directory](https://restic.readthedocs.io/en/latest/030_preparing_a_new_repo.html#local)
+- [sftp server (via SSH)](https://restic.readthedocs.io/en/latest/030_preparing_a_new_repo.html#sftp)
+- [HTTP REST server](https://restic.readthedocs.io/en/latest/030_preparing_a_new_repo.html#rest-server) ([protocol](doc/100_references.rst#rest-backend), [rest-server](https://github.com/restic/rest-server))
+- [AWS S3](https://restic.readthedocs.io/en/latest/030_preparing_a_new_repo.html#amazon-s3) (either from Amazon or using the [Minio](https://minio.io) server)
+- [OpenStack Swift](https://restic.readthedocs.io/en/latest/030_preparing_a_new_repo.html#openstack-swift)
+- [BackBlaze B2](https://restic.readthedocs.io/en/latest/030_preparing_a_new_repo.html#backblaze-b2)
+- [Microsoft Azure Blob Storage](https://restic.readthedocs.io/en/latest/030_preparing_a_new_repo.html#microsoft-azure-blob-storage)
+- [Google Cloud Storage](https://restic.readthedocs.io/en/latest/030_preparing_a_new_repo.html#google-cloud-storage)
+- And many other services via the [rclone](https://rclone.org) [Backend](https://restic.readthedocs.io/en/latest/030_preparing_a_new_repo.html#other-services-via-rclone)
+
+# Design Principles
+
+Restic is a program that does backups right and was designed with the
+following principles in mind:
+
+-  **Easy:** Doing backups should be a frictionless process, otherwise
+   you might be tempted to skip it. Restic should be easy to configure
+   and use, so that, in the event of a data loss, you can just restore
+   it. Likewise, restoring data should not be complicated.
+
+-  **Fast**: Backing up your data with restic should only be limited by
+   your network or hard disk bandwidth so that you can backup your files
+   every day. Nobody does backups if it takes too much time. Restoring
+   backups should only transfer data that is needed for the files that
+   are to be restored, so that this process is also fast.
+
+-  **Verifiable**: Much more important than backup is restore, so restic
+   enables you to easily verify that all data can be restored.
+
+-  **Secure**: Restic uses cryptography to guarantee confidentiality and
+   integrity of your data. The location the backup data is stored is
+   assumed not to be a trusted environment (e.g. a shared space where
+   others like system administrators are able to access your backups).
+   Restic is built to secure your data against such attackers.
+
+-  **Efficient**: With the growth of data, additional snapshots should
+   only take the storage of the actual increment. Even more, duplicate
+   data should be de-duplicated before it is actually written to the
+   storage back end to save precious backup space.
+
+# Reproducible Builds
+
+The binaries released with each restic version starting at 0.6.1 are
+[reproducible](https://reproducible-builds.org/), which means that you can
+reproduce a byte identical version from the source code for that
+release. Instructions on how to do that are contained in the
+[builder repository](https://github.com/restic/builder).

+Enhancement: Add command for copying snapshots between repositories
+
+We've added a copy command, allowing you to copy snapshots from one

+
+Note that this process will have to read (download) and write (upload) the
+entire snapshot(s) due to the different encryption keys used on the source

+which may break deduplication between files already stored in the
+destination repo and files copied there using this command.
+
+To fully support deduplication between repositories when the copy command is
+used, the init command now supports the `--copy-chunker-params` option,

+Fixes "not enough cache capacity" error during restore:

+
+NOTE: This new implementation does not guarantee order in which blobs
+are written to the target files and, for example, the last blob of a
+file can be written to the file before any of the preceeding file blobs.
+It is therefore possible to have gaps in the data written to the target
+files if restore fails or interrupted by the user.
+
+The implementation will try to preallocate space for the restored files
+on the filesystem to prevent file fragmentation. This ensures good read
+performance for large files, like for example VM images. If preallocating
+space is not supported by the filesystem, then this step is silently skipped.

+Bugfix: Make `backup` and `tag` commands separate tags by comma
+
+Running `restic backup --tag foo,bar` previously created snapshots with one
+single tag containing a comma (`foo,bar`) instead of two tags (`foo`, `bar`).
+
+Similarly, the `tag` command's `--set`, `--add` and `--remove` options would
+treat `foo,bar` as one tag instead of two tags. This was inconsistent with
+other commands and often unexpected when one intended `foo,bar` to mean two

+
+To be consistent in all commands, restic now interprets `foo,bar` to mean two
+separate tags (`foo` and `bar`) instead of one tag (`foo,bar`) everywhere,
+including in the `backup` and `tag` commands.
+
+NOTE: This change might result in unexpected behavior in cases where you use
+the `forget` command and filter on tags like `foo,bar`. Snapshots previously
+backed up with `--tag foo,bar` will still not match that filter, but snapshots
+saved from now on will match that filter.
+
+To replace `foo,bar` tags with `foo` and `bar` tags in old snapshots, you can
+first generate a list of the relevant snapshots using a command like:
+
+    restic snapshots --json --quiet | jq '.[] | select(contains({tags: ["foo,bar"]})) | .id'
+
+and then use `restic tag --set foo --set bar snapshotID [...]` to set the new

+Enhancement: Allow usage of deprecated S3 `ListObjects` API
+
+Some S3 API implementations, e.g. Ceph before version 14.2.5, have a broken
+`ListObjectsV2` implementation which causes problems for restic when using
+their API endpoints. When a broken server implementation is used, restic prints
+errors similar to the following:
+
+    List() returned error: Truncated response should have continuation token set
+
+As a temporary workaround, restic now allows using the older `ListObjects`
+endpoint by setting the `s3.list-objects-v1` extended option, for instance:
+
+    restic -o s3.list-objects-v1=true snapshots
+
+Please note that this option may be removed in future versions of restic.

+Change: Deleting files on Google Drive now moves them to the trash
+
+When deleting files on Google Drive via the `rclone` backend, restic used to
+bypass the trash folder required that one used the `-o rclone.args` option to
+enable usage of the trash folder. This ensured that deleted files in Google
+Drive were not kept indefinitely in the trash folder. However, since Google
+Drive's trash retention policy changed to deleting trashed files after 30 days,
+this is no longer needed.
+
+Restic now leaves it up to rclone and its configuration to use or not use the
+trash folder when deleting files. The default is to use the trash folder, as
+of rclone 1.53.2. To re-enable the restic 0.11 behavior, set the
+`RCLONE_DRIVE_USE_TRASH` environment variable or change the rclone
+configuration. See the rclone documentation for more details.

+Bugfix: Correct statistics for overlapping targets

+Enhancement: Improve `prune` performance and make it more customizable
+
+The `prune` command is now much faster. This is especially the case for remote
+repositories or repositories with not much data to remove. Also the memory
+usage of the `prune` command is now reduced.
+
+Restic used to rebuild the index from scratch after pruning. This could lead
+to missing packs in the index in some cases for eventually consistent backends
+such as e.g. AWS S3. This behavior is now changed and the index rebuilding
+uses the information already known by `prune`.
+
+By default, the `prune` command no longer removes all unused data. This
+behavior can be fine-tuned by new options, like the acceptable amount of
+unused space or the maximum size of data to reorganize. For more details,
+please see https://restic.readthedocs.io/en/stable/060_forget.html .
+
+Moreover, `prune` now accepts the `--dry-run` option and also running
+`forget --dry-run --prune` will show what `prune` would do.
+
+This enhancement also fixes several open issues, e.g.:
