Benefits of Microsoft Access MDB and ACCDB file recovery online service
If a Microsoft Access database is damaged, it is crucial to quickly and efficiently recover data, forms, reports, and more. It can be done using the classic Recovery Toolbox for Access software or the online recovery service at https://access.recoverytoolbox.com/online/. But the online recovery service for damaged Access data has many advantages that are convenient for most users:
- Works on all devices
The online service is available from any device—a computer, laptop, tablet, or smartphone. All you need is a modern browser on your device. If trouble catches you outside of work, you can do everything right from your phone anywhere.
- Compatible with all operating systems
The online tool works in any operating system: Windows, macOS, Android, iOS, Linux, and others. The main requirement is a modern web browser (Chrome, Firefox, Safari, etc.).
- Minimal steps to recover a corrupted database
The online file recovery process is as fast and straightforward as possible. There is no need to understand settings, installation or licensing - upload the damaged file and wait for the result.
- No installation of third-party programs is required
Unlike the desktop program, the online service does not require additional software installation, such as Microsoft Access and Recovery Toolbox for Access. It is especially convenient if you work on a device you can't or don't want to install (for example, a corporate laptop or someone else's computer).
- Does not require Microsoft Access installed
Microsoft Access is not necessary to use the online service. You can save the recovered data in a format suitable for further work, even if you do not have Microsoft Access installed on your computer.
- Low cost of recovery
Online recovery costs only $10 for a single file up to 1 GB in size. It is a bargain compared to purchasing a $27 personal license of Recovery Toolbox for Access, especially if you only need to recover one or a few files.
Conclusion:
The online service for recovering corrupt Microsoft Access MDB and ACCDB files is a convenient, affordable, and versatile alternative to the Recovery Toolbox for Access desktop software. It is suitable for more users who need to quickly and easily regain access to corrupt Microsoft Access data in MDB and/or ACCDB files.
Practical testing of damaged Microsoft Access database recovery: comparison of offline programs and online tools
Several times a year, Recovery Toolbox conducts applied testing of solutions for recovering data from Microsoft Access files. The main task is to understand how effectively each solution restores real tables, links, and records, as well as what steps will help improve the performance of Recovery Toolbox for Access and the online service of the same name.
The tests are based not on synthetic examples, but on real user databases that customers upload to the cloud recovery platform (the online service Recovery Toolbox for Access). This approach makes the tests as close to real life as possible and allows us to see real damage scenarios rather than laboratory cases.
How testing is organized:
- Frequency: approximately 1–2 rounds per year.
- Sample: each run includes at least 200–300 files, varying in:
- format: .mdb and .accdb;
- Access version (from older releases to Microsoft 365);
- size (from small files to large databases);
- types of damage and sources of problems.
- Anonymization: personal data and service information are masked; analysis is based on technical characteristics, not content.
In each case, at least 200-300 databases are selected for testing, differing in format (.accdb, .mdb), Microsoft Access version, size, and type of damage. Files can have a variety of defects: from broken slide structures and distorted images to loss of text data and damaged macros.
Real users send damaged databases that have been affected by a variety of factors, such as incorrect program shutdowns, saving failures, damaged data carriers, or virus attacks. This real-world sample of damaged Microsoft Access databases makes testing as close to real-world conditions as possible and allows us to objectively assess which solutions can truly help real users.
Preparation and selection of test files for testing Access database recovery
For testing, we used the most diverse set of damaged Access databases possible. The files were not filtered or pre-sorted in any way — absolutely everything that was downloaded several weeks before the test began was included in the test. This approach allowed us to make the test conditions as close as possible to real-life scenarios, when a user needs to recover data without prior preparation.
The test set included databases with different types of damage:
- Databases that cannot be opened at all;
- Databases with partially compromised data integrity;
- Databases with partial data loss;
- Databases with damaged forms;
- Databases requiring a password.
The test set of damaged databases included files created in various versions of Access (from old *.mdb formats to modern *.accdb formats), with different sizes and structures. We deliberately did not exclude password-protected files in order to evaluate how the utilities cope with such cases.
Software and services involved in the test
During testing, we checked the performance of both desktop programs and cloud-based online services for database recovery. These included:
- Recovery Toolbox for Access – https://access.recoverytoolbox.com/
- Online version of Recovery Toolbox – https://access.recoverytoolbox.com/online/
- MDB Repair Kit + OnlineFile.Repair – https://www.onlinefile.repair/access
- OnlineFileRepair.com – https://onlinefilerepair.com/access
- SecureRecovery® for Access
- AccessFIX
- Stellar Repair for Access
What exactly is checked
Programs and online tools, including Recovery Toolbox products, are compared. For each file, the following is recorded:
- Degree of structure recovery: tables, fields, data types, indexes, relationships, queries, forms, and reports.
- Data integrity: percentage of correctly extracted records, absence of broken rows and duplicates, validity of referential integrity.
- Working with complex fields: Memo/Long Text, OLE Object, attachments, auto-numbering.
- Behavior with different types of damage:
- breakage of system tables (MSys*),
- destruction of indexes and B-trees,
- schema violations (change of field types/lengths),
- breakage of links between tables,
- partial loss of content in large text fields,
- macro and module failures.
- Practical metrics: time to first result, process stability, interface clarity, resource requirements, cost.
This approach gave us a clear comparison showing which solutions are best at recovering Access files from different damaged databases.
Final results of applied testing of Microsoft Access database recovery tools
As part of the study, we collected and analyzed the performance of desktop programs and online services that recover Access databases. All results were converted to a single format, normalized according to the same criteria, and compiled into a single comparative matrix. This allowed us to objectively evaluate how each solution copes with real files and real types of damage.
| Service or program | % of files successfully recovered | Price for recovering 1 file | Comment |
|---|---|---|---|
| Online service Recovery Toolbox https://access.recoverytoolbox.com/online/ | ~67% | $10 per 1 GB | Universal utility for all devices and systems. |
| Recovery Toolbox for Access | ~64% | $25 | For Windows only |
| Online service Online.repair | ~65% | $10 per 1 GB | In addition to the service, there is a Windows utility: MDB Repair Kit |
| Online service OnlineFileRepair.com | ~64% | $5 per 1 GB | |
| SecureRecovery® for Access | ~19% | $59.99 | There is an online service |
| AccessFIX | ~16% | $39 | There is a batch mode for processing large numbers of Access files |
| Stellar Repair for Access | ~9% | $99 | Crashes very often |
Additional information and notes:
- The cost of a SecureRecovery® for Access license is comparable to the cost of recovering a single file through an online service. This may not be cost-effective if you only need to recover one document, but it is cost-effective for large volumes of work.
- Stellar Repair for Access often freezes during operation and sometimes displays uninformative or confusing error messages, which can complicate database recovery for inexperienced users.
Customer's reviews and ratings:
very good
super
One user entering manual watch times in a problem heat. Another user simultaneously in the same event was reviewing (no editing) “by lane” view all other times, and then clicked back to normal “by heat” view.
We use Hy-Tek Meet Manager for swimming and access db go corrupted by multiple uses trying to edit file at one time. I really was not successful restoring it using your software due to not knowing what tables to attempt and/or highly customized db type. We will probably start using SQL express in the future to avoid potential issues with shared DB files.
Muito bom! gostei muito!
Very good
The Access 2003 database have been damaged during a transfer wit Wetransfer. But was fixed here online. Thx!
very helpful
It recovered 85% of my flashdrive trashed Microsoft Access file. I would use it again.
nice
Great, I am 110% satisfied. Thank you for Recovery Toolbox
nice work this apps
Two Windows workstations were logged in to a small but critical Access database, one using Office 2007 and the other Office 365 local. There was a power outage and UPSs died before PCs could be logged out properly. After power was restored none of the tools provided by Microsoft could recover the corrupted accdb file. Thankfully RT got everything back, and UPSs all have nice fresh batteries now.
5 tables out of 93 were restored only partially. The rest of the tables the program fixed well. I wrote to technical support: they tried for a long time, but could not fix it.
It works. Recommended.
I recently used Recovery Toolbox for a data recovery situation, and I was extremely impressed with the results. The software was user-friendly and straightforward to use, making the entire process stress-free. The recovery was successful, and I was able to retrieve all of my important files without any issues. I highly recommend Recovery Toolbox to anyone who needs to recover lost or damaged data.
The file was damaged when my computer froze while the database was open. I had to force a reboot and after the computer came back on, the database was damaged.
I was running a MS Access file directly from dropbox this worked for several years, it was setup so every time the DB was updated dropbox backed the DB up. Last week the DB became corrupted and no recovery tool could repair it, I tried them all belive me. I lost 12 days of data as I was able to use a older file. I have now changed and tested the DB. It now gets backed up once a day and runs from my PC rather than dropbox. This is working a lot better and use idrive for the backup which has a free 10gb option. So the worst that will now happen is I loose one day of data.
The recovery tool was able to restart the database and to give me access to the Data.
Unfortunetaly the primary and foreign keys and indexes were not recovered (name changed) and the Database was not functionnal at all.
I had to take the Data from the recovery and to reimport them in a previous backup.
So I am a little disapointed even if restoring has avoided several hours of work
it can repair Access 2007 MDB file well
Write on the Errors page that you can fix the "Invalid argument" error. First I installed the demo version and waited for the preview (it took about 3 hours). After the data I saw, I bought a license and the program asked me to restart everything again. In general, I spent 6-7 hours, when it could be done 3 hours faster.
The software helped me repair my Access 2007 DB. Simple steps to fix. I recommend
Even the portable version of the program was not useful, as the online repairing quickly fixed the errors of the .accdb file.
The program checked the file and fixed errors in it. If I could select the tables I needed, I would probably spend less time repairing the file. Think about it
MS Access unable to read the .MDF file which was modified less than an hour ago. The breakdown occurred due to a change in the form and in part of the logic in macros. After repaired, I was left without a form and macros :D, but with a working file.
Can't use this Microsoft Access for big projects, it always breaks, problems with save the .mdb file correctly. If not for you, I probably would not have been able to pass my term paper at the university. My database broke at the last moment, when there was a week left before the project was delivered. Thanks for repairing
My .mdb file needs some errors fixes. I'm lucky that you can repair any version of Access file. I have Access 2007, I was able to fix the corrupted file
Access displays an error message when trying to open a database, and most importantly, the error is not written in Latin, but in some incomprehensible hieroglyphs. The base does not respond to the queries, even through macros. I was advised your program on the Access forum. The demo version of the program repairs the database, but I have not decided to buy yet, since it does not fix its forms.
To fix error "3197 no table found" in Access, I had to spend a lot of time for repair MS Access database by online.
After VB coding, my query broke .MDF file. While I try to open file, Access reports error "Query 'turists" is corrupt" and other tables also corrupted. I used step-by-step instruction for recover but for unknown reason, in some cells in table missing data.
MS Access 2003 crashes with a critical error into the system because the form has stopped working. In VBA, forms open, but when you save, the result is the same. I decided to restore and redo everything in MS Access 2010 so that there was a .ACCDB format, but when fixing the file, I could not restore the last form from 7. As a result, I had to pick it up and manually register it in MS Access 2010 with VBA code.
I was looking for a program to restore Access on Windows 32-bit for a long time. The program restored all forms in the .MDB file, but in the "register" and "enter" forms, the password fields were replaced with a simple text field.
Fixing Access 2007 database with "Compact and Repair Database" command doesn't work any more. As it turned out, the file was just corrupted. After restoring my .ACCDB file, everything worked, the main thing is that the forms did not recover, but the database is in good condition. Thanks.
Its really work, because I can repair the selected database from the deleted Access file which one I recover from hard disk. And $27 for repair damaged MS Access 2010 accdb file cheaper than I would give it to IT specialist. Good job!
I had some dozens of corrupted .MDB files. I used Recovery Toolbox for Access, it restored them all for couple minutes.
+ Quite easy interface in comparison with other recovery tools for MS Access.
- Tool is smart money, nothing in excess...
Wonderful tool. I didn't expect such tremendous result. Tables, queries and data was restored by Recovery Toolbox for Access.
