Undelete for InterBase and Firebird 2.5

Undelete for InterBase and Firebird

Undelete for InterBase and Firebird is a specialized data recovery utility designed to restore accidentally deleted records from InterBase and Firebird databases. It analyzes database files at a low level, locating record versions that have been marked as deleted but not yet garbage-collected, and lets you preview and selectively recover them. To keep your data safe, it works in read-only mode on the source file and outputs recovered data via controlled restore or export options.

Key features

• Recovers recently deleted rows from InterBase and Firebird databases before they are overwritten or swept
• Read-only scanning of the source database file to avoid additional damage
• Preview of recoverable records with filtering by table and other criteria
• Selective restore to a database or export to formats such as SQL scripts and CSV
• Support for large databases with progress indicators and detailed logs
• Wizard-style workflow to guide you through scan, review, and recovery
• Attempts recovery of common data types, including text and BLOB fields where feasible

Typical use cases

• Accidental DELETE operations without a recent backup
• Recovery of data removed during maintenance or by erroneous scripts
• Forensic review of recently removed records

Important notes and limitations

• Recovery success depends on how quickly you act: once pages are reused or garbage collection completes, deleted data may be irrecoverable
• Always work on a copy of the database file (.gdb/.fdb) to preserve the original
• This tool is not a substitute for a proper backup and restore strategy

Suggested workflow

1. Immediately stop activity on the affected database and make a file-level copy
2. Scan the copy to identify recoverable records
3. Preview results, filter by table, and choose what to recover
4. Restore selected records or export them to scripts/files for controlled reinsertion

This concise, cautious approach helps you maximize the chance of recovering lost data while minimizing additional risk to your InterBase or Firebird environment.
