WHY EOB

Four reasons to choose EOB

Your cloud data, kept somewhere other than the cloud. A backup that Japanese companies can rely on.

🏠

Your data stays with you

Backups go to your file servers, NAS or PCs. Your data is not handed to an overseas cloud, and costs do not grow with data volume. Made for government, finance and manufacturing, where information must not leave the organization.

📂

Plain files, open them right away

Saved in their original format, in the same folder structure as SharePoint. Open them in Word or Excel and take out just the files you need. No "we can't get it back" moment, even without the vendor.

⚡

Fast, with measured numbers

From the second run, only changed lists, items and files are read. Using SharePoint's change log, deletions and renames are never missed. We always show speed in numbers.

🗾

Start today, with Japanese support

The interface, manual and support are all in Japanese. Just download and place it to start, with no sales meeting required. File names in Japanese and with symbols are tested.

HOW IT WORKS

Daily backups in three steps

1️⃣

Place and connect

Just extract the ZIP. Create a certificate in EOB and register it in Microsoft Entra ID. Planned "Easy initial setup", which finishes the registration with a single administrator sign-in, is in preparation.

2️⃣

Select sites

After you sign in, your sites are shown as a tree. Just check the sites to back up. Newly created sites can also be included automatically.

3️⃣

Automatic, every day

Run the command-line tool (EOBCmd) from Windows Task Scheduler. From the second run only changes are read, so daily backups finish quickly.

SPEED

Repeat backups, dramatically faster

In ver 2.0.6, now in development, unchanged lists are skipped without being read, and changed lists are read only for the changed items and files. We have confirmed that the result matches a full re-read, item by item and field by field.

COMPARE

How EOB differs from Microsoft 365's built-in features and cloud-based services

	EOB	Microsoft 365 built-in features (recycle bin, version history)	Typical cloud-based backup services
Where data is stored	On your premises (in-house servers, NAS, PCs)	Inside Microsoft 365	The provider's cloud
Opens without special tools or services	● (plain files)	—	Restore through the service
Kept beyond 93 days after deletion	●	— (recycle bin up to 93 days)	●
Usable when Microsoft 365 is unreachable	●	—	Depends on the service
Only changes from the second run	● (2.0.6 in development)	—	Depends on the service
Costs do not grow with data volume	●	Within Microsoft 365 storage	Depends on the service
Published prices, payable in yen	●	—	Often quote-based
Japanese interface, manual and support	●	●	Depends on the service
Restore to SharePoint	In development for ver 2 (easy restore)	Within recycle bin and version history	●

Our research (November 2026). Details of cloud-based services vary by service.

DID YOU KNOW?

Microsoft 365 needs backup, too

The standard features of Microsoft 365 do not let you go back to any point, at any time.

🤝

Your data is your responsibility

Under Microsoft's shared responsibility model, managing your data is the customer's responsibility in every type of cloud service.

🗑️

The recycle bin keeps items for 93 days

Deleted files can be restored from the recycle bin, but after 93 days they are permanently deleted and cannot be recovered.

🔐

Ransomware and mistakes

If a PC is infected with ransomware, or someone overwrites or deletes many files by mistake, the changes are synced straight to the files in SharePoint and OneDrive.

👤

OneDrive of people who have left

When an account is deleted, that person's OneDrive is also deleted after a retention period (30 days by default). You can back up important files left in OneDrive all at once (Professional Plus).

📁

Keep a record of a point in time

Some documents, such as records with a legal retention period, require that you can check the information as it was at a given time. With EOB, tasks with separate destinations let you keep backups side by side, for example one per weekday or one per month.

🌐

When you cannot connect

During a network outage or when Microsoft 365 is unreachable, you can keep working with your local backup.

COMING NEXT

Beyond protecting: restoring and migrating

From "keeping files on hand" to a tool that protects, restores and migrates SharePoint as a whole.

↩️

Easy restore In development for ver 2

Put files and lists saved by EOB back into SharePoint, restoring created and modified dates and authors as closely as possible. Our most requested feature, delivered within ver 2. In the development build, we restored a 5,200-item list in 2 min 17 s (parallel degree 4) and 455 files in about 2 min 40 s, and confirmed that every item matches the original (in-house measurement).

🏢
