JamBalaya56562andClaude Opus 4.8 c267edaf89 Reset restore rendezvous barriers per operation
The new restore engine uses two process-wide static TaskCompletionSources as
synchronization barriers in Restore/FileProcessor.cs: file_processor_continue
(the folder-metadata rendezvous) and priority_files_completed. Their counters
are reset at the start of each restore, but the TaskCompletionSources were only
created once at field initialization and were never reset.

After the first restore in a process completes the folder-metadata rendezvous,
its TaskCompletionSource stays completed, so on the second and later restores in
the same process the rendezvous "await" returns immediately and no longer waits
for all file content to be restored before folder metadata (including Windows
ACLs) is applied. This lost ordering guarantee (introduced by #6079) causes
intermittent folder metadata/permission restore failures, observed as the flaky
Issue6068FileAndFolderAttributesAndPermissions unit test on the Windows CI runner.

Reset both TaskCompletionSources in RestoreHandler before the FileLister/
FileProcessor tasks are started (so there is no race), alongside the existing
counter reset. file_processor_continue is the demonstrated root cause;
priority_files_completed has the identical never-reset pattern and is reset
defensively.

Verified locally on .NET 10: before the reset, file_processor_continue is already
completed on the 2nd+ restore in a process; the Issue6068 suite passes repeatedly.

Features

  • Duplicati uses AES-256 encryption (or GNU Privacy Guard) to secure all data before uploading.
  • Only initial backup is with full contents, all additional backups are differential to save bandwidth and storage
  • Built-in scheduler ensures backups stay up-to-date automatically.
  • An integrated updater notifies you of new releases.
  • Encrypted backups can be transferred to destinations like FTP, WebDAV, SSH (SFTP), Amazon S3, and more.
  • Flexible backup options: back up folders, specific file types (e.g., documents or images), or use custom filters.
  • Available as a user-friendly application or a command-line tool.
  • Supports backing up open or locked files using Volume Snapshot Service (VSS) on Windows or Logical Volume Manager (LVM) on Linux.
  • Advanced options for filters, deletion rules, transfer settings, bandwidth limits, and more.

Why Use Duplicati?

Keep your data safe, store it remotely, and back it up regularly! Many backup solutions fail to meet these essential requirements, but Duplicati excels at all three:

  • Keep your data safe: Duplicati uses strong encryption to ensure your data remains private. With a secure password, your backup files are safer on a public web server than unencrypted files at home.
  • Store your backup remotely: Protect your data from local disasters like fires by storing backups on remote servers. Duplicati supports incremental backups, making it efficient to use distant storage destinations.
  • Backup regularly: Outdated backups are as good as no backups. Duplicati's built-in scheduler ensures your backups are always current. It also uses compression and incremental backups to save storage and bandwidth.
