Enhancement: Allow AWS Assume Role to be used for S3 backend
|
||||
|
||||
Previously only credentials discovered via the Minio discovery methods
|
||||
were used to authenticate.
|
||||
|
||||
However, there are many circumstances where the discovered credentials have
|
||||
lower permissions and need to assume a specific role. This is now possible
|
||||
using the following new environment variables.
|
||||
|
||||
- RESTIC_AWS_ASSUME_ROLE_ARN
|
||||
- RESTIC_AWS_ASSUME_ROLE_SESSION_NAME
|
||||
- RESTIC_AWS_ASSUME_ROLE_EXTERNAL_ID
|
||||
- RESTIC_AWS_ASSUME_ROLE_REGION (defaults to us-east-1)
|
||||
- RESTIC_AWS_ASSUME_ROLE_POLICY
|
||||
- RESTIC_AWS_ASSUME_ROLE_STS_ENDPOINT

Bugfix: Improve errors for irregular files on Windows
|
||||
|
||||
Since Go 1.21, most filesystem reparse points on Windows are considered to be
|
||||
irregular files. This caused restic to show an `error: invalid node type ""`
|
||||
error message for those files.
|
||||
|
||||
We have improved the error message to include the file path for those files:
|
||||
`error: nodeFromFileInfo path/to/file: unsupported file type "irregular"`.
|
||||
As irregular files are not required to behave like regular files, it is not
|
||||
possible to provide a generic way to back up those files.

Bugfix: support backup of deduplicated files on Windows again
|
||||
|
||||
With the official release builds of restic 0.16.1 and 0.16.2, it was not
|
||||
possible to back up files that were deduplicated by the corresponding Windows
|
||||
Server feature. This also applies to restic versions built using Go
|
||||
1.21.0 - 1.21.4.
|
||||
|
||||
We have updated the used Go version to fix this.

Bugfix: Improve error handling for `rclone` backend
|
||||
|
||||
Since restic 0.16.0, if rclone encountered an error while listing files,
|
||||
this could in rare circumstances cause restic to assume that there are no
|
||||
files. Although unlikely, this situation could result in data loss if it
|
||||
were to happen right when the `prune` command is listing existing snapshots.
|
||||
|
||||
Error handling has now been improved to detect and work around this case.

Enhancement: Add bitrot detection to `diff` command
|
||||
|
||||
The output of the `diff` command now includes the modifier `?` for files
|
||||
to indicate bitrot in backed up files. It will appear whenever there is a
|
||||
difference in content while the metadata is exactly the same. Since files with
|
||||
unchanged metadata are normally not read again when creating a backup, the
|
||||
detection is only effective if the right-hand side of the diff has been created
|
||||
with "backup --force".

Bugfix: Correct restore progress information if an error occurs
|
||||
|
||||
If an error occurred while restoring a snapshot, this could cause the restore
|
||||
progress bar to show incorrect information. In addition, if a data file could
|
||||
not be loaded completely, then errors would also be reported for some already
|
||||
restored files.
|
||||
|
||||
We have improved the error reporting of the restore command to be more accurate.

Bugfix: Improve reliability of restoring large files
|
||||
|
||||
In some cases restic failed to restore large files that frequently contain the
|
||||
same file chunk. In combination with certain backends, this could result in
|
||||
network connection timeouts that caused incomplete restores.
|
||||
|
||||
Restic now includes special handling for such file chunks to ensure reliable
|
||||
restores.
