説明

次の互換性の表を参照してください。(一部日本対象外製品が表記されております。日本でのサポート対象製品はホームページにてご確認願います。)

This article gives description of how backup archives are compatible with different versions of Acronis backup software

Symptoms

Backup or a different operation (replication, recovery, etc) fails with the following error:

The archive is invalid or its type is unsupported

You start a backup plan for the first time. After the first backup has not completed (for any reason), you want to delete this incomplete archive, but cannot find it under Backups. Or you notice, that space used in Acronis Cloud is larger than your backups occupy.

Solution

Deleting an entire backup:

  1. Connect to Management Console, and go to Backups tab, and then Locations

Symptoms

  1. You have a backup plan with replication. Backup format is set to Automatic selection in Backup options.
  2. The resulting archive is in Version 11 format as the original archive was created by older product version
  3. After the archive is deleted in original location, replication fails with the following error:

    Cannot use this type of backup archive.

Once a password has been set for a backup archive, it can not be retrieved if lost or forgotten

In what way full, differential and incremental backups differ from each other

This article applies only to archives in TIB format
If you have questions about the new tibx archives in Acronis True Image, see Acronis True Image 2020: new tibx backup format FAQ

Introduction

Acronis True Image 2020 introduced a new backup format - .tibx, which is even more reliable and convenient. The .tibx format is used for disk backups created to internal drives, external drives, network storage. 

One of the main changes in this new backup format is that the .tibx format saves full and differential backup versions as separate files, while incremental backup versions are automatically merged into their base full backups.

Description

  1. You create a backup using Version 12 format.
  2. An operation with archive (e.g. applying retention rules) fails with the error message

    Failed to lock the file

  1. バージョン 12 形式を使用してバックアップを作成します。
  2. 以下のエラーメッセージが表示され、アーカイブを使う操作(例えば、保持ルールの適用など)に失敗します:

    「ファイルのロックに失敗しました。」
