The most dependable route is to restore a usable backup chain to a separate database at a point before the deletion, then validate and extract the missing rows. If no suitable backup chain exists, transaction-log or data-file analysis may be worth investigating, but success depends on what evidence remains; recovery is not guaranteed.
Why recovery may still be possible without CDC or audit
CDC and auditing can preserve change history in forms designed for later review, but they are not the only possible sources of evidence. Microsoft states: “Every SQL Server database has a transaction log that records all transactions and the database modifications that are made by each transaction.” Whether records relevant to a particular deletion remain available is a separate matter.
The practical distinction is between restoring a known-good backup sequence to a time before the delete, and trying to interpret surviving log or database-file contents. The first is a documented SQL Server restore process when the necessary backups exist. File or log analysis is more incident-dependent and should be treated as uncertain until recovered values are checked.
First, preserve evidence and establish what happened
Avoid unnecessary writes or maintenance that could change relevant log or data pages. Where operationally possible, preserve copies of database and log files before attempting file-based analysis. Do not experiment on the only copy, and do not overwrite production with an unverified recovery result.

Record these details before choosing a route:
- SQL Server version and the database’s recovery model.
- The deletion time, including its timezone, and the affected table and keys.
- Subsequent database activity and any maintenance or recovery actions already taken.
- Which full, differential, and transaction-log backups exist, including whether the log-backup sequence is complete.
These are also the kinds of details ApexSQL support asks for when assessing a recovery case; see its recovery support checklist.
Route 1: Restore a backup chain to before the delete
If you have a usable backup sequence that reaches the required time, restore it as a separate database. This lets you inspect the earlier rows without rolling production back or discarding later valid activity. Microsoft documents point-in-time restore for the full and bulk-logged recovery models. A log backup containing bulk-logged operations has a key limitation: SQL Server does not allow a stop point inside that backup.
What the backup sequence needs
For a full-recovery database, the usual sequence is the appropriate full backup, any required differential backup, and every subsequent transaction-log backup through the target time. Apply the log backups chronologically. A missing or damaged log backup limits how far the chain can take you. Keep the restore sequence in a state that allows more logs to be applied; recovering the database too early ends that sequence.
Microsoft explains the order and restore state in Apply Transaction Log Backups and describes the point-in-time process in Restore a SQL Server Database to a Point in Time. The cited point-in-time guidance covers full and bulk-logged models, not the simple recovery model.

Restore and extract without replacing production
- Choose a full backup and, if applicable, a differential backup that precede the deletion.
- Restore them to a separate database, not over the production database.
- Apply each subsequent log backup in order, leaving the database unrecovered while more logs remain to be applied.
- Stop at a point before the delete, then recover the restored copy once the intended logs have been applied. Follow Microsoft’s model-specific instructions, especially if the database uses bulk-logged recovery.
- Compare the restored rows with production using primary keys and business constraints. Check for later valid updates or deletes and for dependent rows before scripting or copying only the records that are actually missing.
If you need a log-sequence-number recovery point rather than a time-based target, Microsoft describes the option and related backup metadata in Recover to a Log Sequence Number.
Route 2: Investigate logs, backups, or database files
If a backup chain cannot reach the time before the deletion, inspect what else remains: the online transaction log, retained detached log files, backups, or copies of the database data files. A specialist tool may be able to analyze some of these sources, but availability and results depend on the incident, the surviving files, and the tool’s capabilities.
Rank #4
For simple recovery mode, ApexSQL describes a method that reads the MDF data file. Its guidance says to take the database offline and copy the MDF and LDF files before analysis; it also warns that complete recovery is not guaranteed and false positives can occur. This is vendor guidance in an article last updated on August 9, 2018, not proof that a particular recovery will work or that current product compatibility is assured. See ApexSQL’s simple-recovery discussion.
Do not treat undocumented internal functions as supported recovery APIs. Keep original files intact, work from copies where possible, and regard any generated rows or scripts as unverified until their values, keys, relationships, and duplicate behavior have been reviewed.
Best Value
How the two recovery routes differ
| Consideration | Backup point-in-time restore | Log or data-file analysis |
|---|---|---|
| Evidence needed | Appropriate full and, where needed, differential backups, plus an uninterrupted sequence of log backups through the target. | Relevant online or detached logs, backups, or data-file contents must still be available; what matters depends on the incident and tool. |
| Recovery model | Microsoft documents point-in-time restore for full and bulk-logged models. Bulk-logged operations can restrict the target point within a log backup. | A vendor describes data-file analysis for simple recovery, but the outcome is case-specific and not guaranteed. |
| Granularity | Restore to a supported time, marked transaction, or log sequence number, depending on the restore sequence and target. | Vendors may claim row-level recovery; verify SQL Server-version support, data type coverage, source files, and recovered output. |
| Operational approach | Restore to a separate database and extract reviewed rows. | Preserve original files, analyze copies, and review generated output before applying it. |
| Confidence | The clearer and more complete the backup chain and target time, the more dependable this documented route is. | Results are less predictable and depend on what remains after the incident. |
When a recovery tool may help
Quest describes ApexSQL Recover as a SQL Server tool that can read transaction logs and backups, recover deleted, dropped, or truncated data, and create rollback or replay scripts. These are vendor-described capabilities, not independently tested results or a guarantee of recovery. Verify current SQL Server-version support and whether the available files fit your case with the vendor before relying on or purchasing the product.
Quest’s ApexSQL Recover FAQ lists a limitation for recovering out-of-row BLOB data from transaction-log files and recommends case-specific trial or pre-sales validation. Confirm current trial terms and assess any generated script before applying it to production.
If the database is damaged, consider the tail of the log
When a database is damaged and preserving its latest activity matters, a tail-log backup may preserve log records that have not yet been backed up, if the scenario permits it. Microsoft explains the conditions and process in its tail-log backup guidance. This is a preservation step, not a substitute for confirming that a usable restore chain or recoverable row data exists.
