Jamku – Data Storage & Security

Jamku – Fastest Office Management Software for CA, CS, CMA, Tax Consultants, Advocates and every professional.

Security is our top most priority

(Hence we have a dedicated page to explain security measures in Jamku)

No System is 100% secure. Even Yahoo, LinkedIn, Facebook had instances of security breaches in past. So, does that mean that nothing is safe? NO. It means nothing is impregnable. It’s a cat and mouse game. We implement best security measures as per industry standards and keep on updating and monitoring these measures. With this introduction, let’s see how Jamku is secured.

Data Security is all about CIAConfidentiality, Integrity, Availability.

Data Confidentiality

Data confidentiality needs to cover data at rest and data in transit.


In Transit

Data during transit from Server-to-Browser and from Browser-to-Server is 100% encrypted using HTTPS Protocol. This is an industry standard for data encryption during transfer.

At Rest

All data resides in the database. The database is encrypted and stored on hard disk using hardware encryption. Thus ensuring full encryption.

Data Integrity

Data integrity can be ensured as a preventive and corrective measure.


All the code written goes for a quality check to ensure it meets performance, security and design parameters. To ensure this and keep track we use GIT for version control.


Data security is considered as a factor even right from designing phase. Whenever a new feature is planned, the dedicated team of CAs and Engineers prepare a blueprint.

Data Availability

Data availiablity is ensured by protection and in case of failure through a backup.


Jamku servers are protected from DOS attacks, by blocking malicious user agents based on machine learning and temporary IP blocking based on requests.



We have 3 plan backup – 2 are automated process, 1 is manual process. Plan A backup is kept in AWS. Plan C backup is kept in our office NAS Box. *Plan B is a secret 🙂 this is also protection measure.

How is my Data Stored?

This is the most common question we get, so here’s how your data is stored.

All the data relating to your office is stored in Buckets (Bucket is a metaphor to avoid using the technical jargons). All these buckets are locked until the user logs into the software.

The below diagram shows how the data is structured and stored.


When a user logs in to jamku, system checks which all buckets the user is authorised for. If the system finds a single office bucket, it will unlock the bucket and allow the user to interact with the data inside the bucket based on the permissions assigned to the user. 

In case, the system finds that the user is authorised to access more than one bucket, then it prompts the user which bucket it wants to login into. Thus, ensuring no unauthorised access to the bucket is possible.

Where is my Data Saved?

Ok, lets answer another commonly asked question

We have purchased the servers from one of the biggest cloud/web hosting company. They store the data in their Tier 3 Data Center which is located in Mumbai. In case of any issue with Mumbai Data Centre, the server is migrated to Banglore Data Centre.

Apart from the main data storage, we keep the backup with AWS, which has a data centre in Mumbai.

What happens if the server goes down?

We aim for 99% uptime but server downtime is inevitable because the server will go down for some reason. Here are some of the safeguards that we have in place.

Preventive Control

KVM architecture

The server sits on top of the KVM architecture which makes it resilient to hardware failures. Every hardware has a redundancy. Eg – in case of a hard disk failure the RAID configuration will kick in and activate the failover SSD.

Monitoring Control


Uptime Robot

We have implemented Uptime Robot to monitor the server uptime. If the server goes down, it immediately notifies the entire development team of Jamku. We then figure out the issue and get the server up and running.

Corrective Control


In an unfortunate event of total failure, we shall restore the backup from our Plan A. If Plan A fails we have a Plan B backup restoration. In case of Plan B failure, the data is restored from Plan C. This may result in data loss of up to 3 hours.

We believe in transparency, hence our uptime monitoring is publicly available for curious minds 🙂

Why 99% and not 100%?

Server software needs to be updated on a regular basis to maintain the best in class security and performance. When the server software is updated, Jamku becomes temporarily unavailable. This will, however, not impact your office functioning because this is scheduled to run at night. Apart from server software updates, we also undertake database tuning and optimization, this also results in a downtime. Be rest assured, these activities are also undertaken at night. Updating the Jamku to next version, may also result in downtime of 1-2 minutes.

Qualys, the industry standard to test the HTTPS, aka encryption during data in transit rated us “A+”.
