Advanced Backup Filters & Options: Aryson Thunderbird Backup Tool
Use the appropriate built-in filter to migrate only the relevant data & increase the processing speed.
Date Range Filter
Back up emails from a specific start and end date instead of processing the entire Thunderbird mailbox. This helps users focus on recent, project-specific, or required emails and avoid creating unnecessarily large backup files.
Duplicate Email Detection
The software finds out duplicate e-mails by utilizing existing mail headers—'To',' 'From', 'Subject', 'Body' and 'Cc'. It thus reduces unnecessary information stored in backups and makes exported mailboxes even neater.
Attachment Handling
Choose how attachments should be handled during backup. Users can include attachments with their emails or exclude them when only the email content is required, helping control backup size and storage usage.
Skip Previously Exported Data
Skip data that has already been exported during an earlier backup operation. This is useful when running repeated backup jobs because users can avoid processing the same mailbox content again and save processing time.
Search & Advanced Search
Search the Thunderbird folder hierarchy and narrow down email data using available To, From, and Subject criteria. This makes it easier to locate specific mailbox content before selecting it for backup.
Preserve Folder Hierarchy
Maintain the original Thunderbird folder and subfolder structure in the exported data. Emails remain organized according to their source folders, making the backup easier to browse and manage later.
Merge MBOX Files
Combine multiple MBOX files into a single MBOX output when you need to consolidate Thunderbird mailbox data. Moreover, you can merge MBOX files based on file size (MB/GB). This can make several mailbox files easier to manage as one backup.
Split Large PST/MBOX Files
Split MBOX/PST output into smaller files based on the selected file size (MB/GB). This helps users manage large Thunderbird backups more conveniently and makes individual output files easier to store or transfer.
Custom Output Location
Select the folder where the Thunderbird backup files should be saved. This gives users control over backup organization and makes it easier to store exported data on a preferred local drive or storage location.
Custom File Naming
Apply available naming options to supported output formats such as EML, MSG, and PDF. This helps users organize exported emails using meaningful names and locate individual messages more easily after backup.
PDF Size Restriction
Control the size of generated PDF output, with the documented limit of up to 500 MB per PDF file. This helps keep PDF archives manageable for storage, sharing, and access.
Email & Attachment Preview
Preview email content and attachments before starting the backup. Users can verify the data they are about to export and select the required messages with greater confidence.
