Production data copied to test environments, laptops and repositories is the most common gap. Shared client credentials in team chats and config files are another. As a processor, deletion at project end must reach every copy your team made.
The first four things to sort out
Mask production data before it reaches test or demo.
Keep client credentials in a vault, not in chat or code.
Scan repositories for personal data and secrets.
Delete client data from laptops and environments at roll-off.
A worked example
Software engineering department
Client credentials in a team chat
Day 1A developer posts a client database password in team chat.
Day 1The message is deleted and the password changed with the client.
Week 1All client credentials move to a vault.
AfterChat is scanned for secrets.
Evidence kept
Chat record
Password change
Vault setup
Credentials belong in a vault, not in chat.
What others in the sector usually do. Many engineering teams add a secret and data scan to every code push.
Where it usually goes wrong, by organisation type
Organisation type
Hotspots
IT services and consulting
Production data copied to laptops or test environments; Shared client credentials in team chats; Sub-contractors working under your client access
BPO and contact centre
Card numbers spoken on recorded calls; Phones and paper on the floor; Outbound calls without consent checks for Indian customers
Global capability centre
Indian customer data mixed into global data sets; Global HR systems hosted abroad; Intra-group agreements that predate DPDP
SaaS and software products
Support staff browsing customer tenants; Analytics on customer data beyond the contract; Deletion that does not reach backups
Managed services, data centres and cloud
Privileged admin access across many clients; Subscriber records kept with no access limits; Backups of client systems held for years
7 questions the Software engineering department asks, answered in full
Short answer: Named, logged and removed at roll-off
Through named accounts, from managed devices or controlled jump servers, with multi-factor sign-in and logging. Access should be removed the day someone rolls off. Client data should stay in client systems and not be copied to laptops, internal tickets or chat.
Short answer: Four questions at design, then build the basics in
Ask four questions at the design stage: what personal data, why, for how long, and who sees it. Then build in what the Act assumes: a notice, consent where needed, role-based access, logs of record views, a way to delete, and a way to answer requests. Adding these after launch costs far more.
From your seat: Software engineering department. Build the four questions into design review.
Short answer: Yes, through a written backup-expiry rule
Deletion should reach every copy you control. For backups, the usual practice is to let deleted records expire with the normal backup cycle, never restore them into live use, and write this down. Test and training copies should use masked data.
From your seat: Software engineering department. Deletion and backup expiry together.
Example in IT and ITeS
Client backups held by managed service teams must follow client retention.
What the law says
Section 8(7) asks for erasure. Rule 6 asks for backups for continuity. The two meet in a backup retention rule that is short enough and written down. Section 8(7) · Rule 8 · Section 8(5) · Rule 6
Steps
List where copies live: backups, replicas, test, analytics, laptops, vendors.
Set backup retention to match the retention schedule.
Write a rule: deleted records are not restored into live systems.
Mask personal data in test and training copies.
Get deletion confirmations from vendors.

Common mistakes
Ten-year backups for convenience
Live copies in test
Restoring old backups and bringing deleted records back
Short answer: At least one year; 180 days of ICT logs in India
Keep logs that show who accessed personal data and what they did, for at least one year under the DPDP Rules. CERT-In separately asks for ICT system logs to be kept for 180 days within India. Logs must be protected so nobody can quietly change them.
From your seat: Software engineering department. Log record views.
Example in IT and ITeS
Keep logs of access to client systems, as well as your own systems.
What the law says
Rule 6 lists logs and monitoring as a minimum safeguard. Rule 8(3) asks for logs to be kept for at least one year. The CERT-In Directions of 2022 ask for 180 days of ICT logs kept within India. Section 8(5) · Rule 6 · Section 8(7) · Rule 8
Steps
List systems holding personal data and what each logs today.
Turn on access logging where it is missing.
Send logs to one protected store, with at least one year of retention.
Keep a copy of ICT logs in India for at least 180 days.
Short answer: Only those who need it, reviewed every quarter
Only people who need it for their job, and only the part they need. Use named accounts, give access by role, review it every quarter and remove it on the day someone leaves. Watch privileged accounts closely.
From your seat: Software engineering department. Roles in the architecture.
Example in IT and ITeS
Your own HRMS and payroll, as well as client systems.
What the law says
Rule 6 names access control as a minimum safeguard, along with logs and monitoring that can detect misuse. Section 8(5) · Rule 6
Steps
Write a role matrix for each key system.
Replace shared logins with named accounts.
Use multi-factor sign-in for admin and remote access.
Short answer: Check every channel; children often appear where you least expect
Anyone under 18 is a child under the Act. For a child's data you need verifiable consent from a parent or lawful guardian, and you must not track, behaviourally monitor or show targeted ads to children. Some classes and purposes are exempt under Rule 12 and the Fourth Schedule, for example healthcare to the extent needed to protect the child's health, and educational institutions for their educational work.
From your seat: Software engineering department. Age checks and tracking switches.
Example in IT and ITeS
Usually only if a client's service involves children, or in staff dependants' records.
What the law says
Section 9 sets the duties. Rule 10 explains how to verify the parent. Rule 12 and the Fourth Schedule list the exemptions. Section 9 · Rules 10, 12 · Section 6
Steps
Find where children's data enters: customers, dependants, interns, visitors, scholarships, app sign-ups.
Decide whether an exemption in the Fourth Schedule applies to that purpose.
Where none applies, add an age question and a parent-consent step.
Switch off tracking and targeted ads for under-18 users.
Record the decision for each channel.
Evidence to keep
Channel-by-channel note on children's data
Parent-consent records
Ad and tracking settings
Common mistakes
Assuming 'we are B2B, so no children'
Using the age 13 or 16 from foreign laws
Treating a tick-box from the child as parental consent
Short answer: Yes, unless a law requires you to keep it
You must erase data that you no longer need for the purpose it was collected for, unless a law requires you to keep it. Where a law does require it, keep the data, stop using it for anything else, and tell the person why it is being kept and until when.
From your seat: Software engineering department. Make deletion an API, not a manual task.
What the law says
Section 12 gives the right to correction and erasure. Section 8(7) allows retention only where a law requires it. Rule 8(3) asks every organisation to keep personal data and logs for at least one year first. Sections 11–14 · Rule 14 · Section 8(7) · Rule 8
Steps
Log the request and verify identity.
Check the retention schedule for each record type involved.
Delete what has no legal reason to stay, including copies with vendors and in test systems.
Mark what must stay, with the law and the end date.
Reply in plain words: what was deleted, what is kept, why and until when.
Evidence to keep
Erasure log
Vendor deletion confirmations
Reply to the person
Common mistakes
Refusing every erasure request 'because of backups'
Deleting records a law requires
Not telling vendors
The sections you will use most
Section 8(5) · Rule 6: Security safeguards. Remote access to client systems, laptops and ticketing tools need control, monitoring and one-year logs.
Report specified cyber incidents within six hours. Keep ICT logs for 180 days within India. Sync clocks to NIC or NPL time servers. Data centres, VPS, cloud and VPN providers keep specified subscriber information for five years.
Breach handling must meet the six-hour CERT-In clock and the DPDP report to the Board. Subscriber records need DPDP-level protection.
CERT-In
DPDP Act, Section 17(1)(d)
Processing of data of people outside India, under a contract with a party outside India, is exempt from most of the Act.
Tag each data set by where the people live. The exemption does not cover Indian staff or Indian customers.
MeitY
IT Act, Section 43A and SPDI Rules, 2011
Reasonable security practices for sensitive personal data, until Section 43A is omitted on 13 May 2027.
Your current ISO 27001 practices meet these today; DPDP Rule 6 takes over from May 2027.
Commercial calls and SMS to Indian numbers must follow registration and preference rules.
Outbound campaigns for Indian clients need both DPDP consent and TRAI compliance.
TRAI
Labour Codes (in force from 21 November 2025)
The four labour codes replaced older labour laws, including registers and records employers must keep.
Set retention for staff records against the new codes and state rules.

Client contracts and foreign laws (for example GDPR for EU clients)
Clients often bind you to their own country's law through contracts and standard clauses.
These are contract duties, not Indian law, but you must meet them alongside DPDP.
