+
+# 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](https://restic.readthedocs.io/en/latest/100_references.html#rest-backend), [rest-server](https://github.com/restic/rest-server))
+- [Amazon 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).

+Bugfix: Do not crash with Synology NAS sftp server
+
+It was found that when restic is used to store data on an sftp server on a
+Synology NAS with a relative path (one which does not start with a slash), it
+may go into an endless loop trying to create directories on the server. We've
+fixed this bug by using a function in the sftp library instead of our own
+implementation.
+
+The bug was discovered because the Synology sftp server behaves erratic with
+non-absolute path (e.g. `home/restic-repo`). This can be resolved by just using
+an absolute path instead (`/home/restic-repo`). We've also added a paragraph in
+the FAQ.

+Enhancement: Self-heal missing file parts during backup of unchanged files
+
+We've improved the resilience of restic to certain types of repository corruption.
+
+For files that are unchanged since the parent snapshot, the backup command now
+verifies that all parts of the files still exist in the repository. Parts that are
+missing, e.g. from a damaged repository, are backed up again. This verification
+was already run for files that were modified since the parent snapshot, but is

+Enhancement: Add command for copying snapshots between repositories
+
+We've added a copy command, allowing you to copy snapshots from one
+repository to another.
+
+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
+and destination repository. Also, the transferred files are not re-chunked,
+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,
+which initializes the new repository with identical parameters for splitting
+files into chunks as an already existing repository. This allows copied

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

+NOTE: This new implementation does not guarantee order in which 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

+Enhancement: Add Alibaba/Aliyun OSS support in the `s3` backend
+
+A new extended option `s3.bucket-lookup` has been added to support
+Alibaba/Aliyun OSS in the `s3` backend. The option can be set to one
+of the following values:
+
+- `auto` - Existing behaviour
+- `dns` - Use DNS style bucket access
+- `path` - Use path style bucket access
+
+To make the `s3` backend work with Alibaba/Aliyun OSS you must set
+`s3.bucket-lookup` to `dns` and set the `s3.region` parameter. For
+example:
+
+    restic -o s3.bucket-lookup=dns -o s3.region=oss-eu-west-1 -r s3:https://oss-eu-west-1.aliyuncs.com/bucketname init
+
+Note that `s3.region` must be set, otherwise the MinIO SDK tries to
+look it up and it seems that Alibaba doesn't support that properly.

+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
+tags.
+
+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
+tags. Please adjust the commands to include real tag names and any additional
+tags, as well as the list of snapshots to process.

+Enhancement: Configurable progress reports for non-interactive terminals
+
+The `backup`, `check` and `prune` commands never printed any progress
+reports on non-interactive terminals. This behavior is now configurable
+using the `RESTIC_PROGRESS_FPS` environment variable. Use for example a
+value of `1` for an update every second, or `0.01666` for an update every

+Enhancement: Allow usage of deprecated S3 `ListObjects` API
+
+Some S3 API implementations, e.g. Ceph before version 14.2.5, have a broken

+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.
