Features | EOB Exceed One Backup

HOW IT WORKS

Select, keep, automate. Your Microsoft 365 data, on hand

Back up SharePoint Online and OneDrive data as plain files to your own servers or NAS. Because the data is kept outside the cloud, it helps you prepare for accidental deletion and ransomware.

☑️

Select

Just pick the sites and OneDrive accounts to back up from the list. Settings can be made per site.

Pick sites

💾

Keep as files

Saved to your servers, NAS or PCs in the same folder structure as the site. Open them as they are, without special software.

Opens as is

⏰

Run automatically

Every night, automatically, with the command-line tool and Task Scheduler. Parallel processing makes it fast, and failures are retried automatically.

Parallel, auto retry

📂

Retrieve and use

Retrieve just the files you need and use them right away. List data and attachments are kept too.

Only what you need

About 61% fasterwith parallel processing (in-house test: 6 min 30 s → 2 min 30 s)

Select sites and back up

After you sign in, the sites in your tenant are shown as a tree. Just check the sites, subsites and folders you want to back up and click "Execute".

Folders are created in the same structure as the site. Save to a local drive or a shared folder on the network (such as your file server or NAS)
Full (Overwrite): also overwrites files that already exist in the destination
Differential: skips files with the same modified date and saves only files that have changed
You can choose whether to also save hidden objects (data with SharePoint's hidden attribute)

Files, lists and attachments

Not only files in document libraries, but also list data and attachments are saved together.

List contents are saved as XML files
List attachments, easily forgotten in manual work, are saved too Fixed in 2.0.4
Files are saved in the same format as in SharePoint. No special compression or conversion, so you can open them as they are without dedicated software and retrieve only the files you need
Supports files larger than 2 GB and paths longer than 260 characters

To put files back into SharePoint, upload the retrieved files to the site. A restore-to-SharePoint feature is under consideration on the Roadmap.

OneDrive and Microsoft 365 groups

With the Professional Plus Edition, you can back up personal sites (OneDrive for Business) and group sites (Microsoft 365 groups) in addition to general sites.

Save important files that are kept only in someone's personal OneDrive
You can also select users and back up only the OneDrive accounts you need

For differences between editions, see Pricing & requirements.

Scheduled automatic backup from the command line

Save the sites and backup method selected in the window to a "batch config file", and run it with the command-line tool (EOBCmd.exe). Register it in Windows Task Scheduler to automate daily or weekly backups.

Automatic mode (/m): backs up all sites that exist at run time. Newly created sites are included automatically
You can specify where to write the log file (/l)
Register separate tasks with different destinations (/f) to keep backups from different points in time side by side, for example per weekday or per month

Command Prompt

EOBCmd.EXE /c:EOBBatch.xml /f:D:\Backup /l:D:\Backup\Log.txt /m:g
/c:	Batch config file
/f:	Backup destination folder
/l:	Log file name (optional)
/m:	Automatic mode (optional)　g all general sites　p all personal sites　o all group sites　a general sites + personal sites

p, o and a are available only in Professional Plus. Automatic mode is not available in the Free Edition.

Certificate authentication 2.0.1

Register an app in Microsoft Entra ID and connect to SharePoint Online with a certificate. Because EOB does not use Azure ACS, which was retired on April 2, 2026, you can keep using it after the retirement.

Create the certificate in EOB under "Config" → "Create certificate" (validity period in years)
"Site Config" runs a connection test before saving, so you notice configuration mistakes right away

Faster and more robust 2.0.2–2.0.3

Processing has been reworked so that even sites with a large number of files are backed up to the end without stopping.

Choose 1 to 4 parallel downloads (default: 2)
Throttling (HTTP 429/503) and temporary network errors are handled by waiting and retrying automatically
Only files that still cannot be saved after retries are skipped and recorded in the log; processing continues
Longer timeouts so that downloads of large files are not cut off
