maintenanceData Backup Service Dhaka — Hard Drive & Cloud Backup
14 July 2026 · 11 min read · BAYAS Editorial
BAYAS provides professional data backup service in Dhaka starting from BDT 1,500 for a home visit. Certified technicians back up your hard drive, SSD, or laptop to an external drive or cloud storage — across 36 Dhaka zones, 8 AM–11 PM, seven days a week.
Losing irreplaceable data — family photos, business files, years of work — is one of the most distressing tech failures. BAYAS has handled 500+ emergency data scenarios since 2018. In most cases, the data was only partially recoverable (or not at all) because no backup existed. A professional backup job takes 1–3 hours and costs a fraction of what data recovery costs after a drive failure.
Key Takeaways
- Starting cost: Professional data backup at home in Dhaka from BDT 1,500 (single drive, up to 500 GB); full PC backup with external drive included from BDT 4,500.

What Is a Professional Data Backup Service?
Definition: A professional data backup service is the process of systematically copying all critical files — documents, photos, videos, databases, and system settings — from your computer's internal storage to a secondary location (external hard drive, USB drive, NAS, or cloud storage), so that a complete restore is possible if the original drive fails, is stolen, or becomes corrupted.
A professional backup differs from simply copying files manually. BAYAS technicians:
- Inventory your drives to identify all critical folders
- Verify data integrity with MD5 checksums before and after
- Organize the backup with a clear folder structure and date-stamped archives
- Test a partial restore to confirm the backup is actually usable
- Set up automated recurring backups (if requested) so you never have to think about it again

Why Dhaka Computers Need Professional Backup
Dhaka's environment creates an unusually high risk of data loss:
Frequent Power Surges and Load Shedding
Bangladesh's power grid experiences regular voltage fluctuations — from as low as 160V to peaks above 280V in some areas. A single unprotected power surge can corrupt a hard drive's file system in milliseconds, even if the drive itself physically survives. BAYAS technicians see 20–30 drive failures per month linked directly to power events.
High Humidity Causes Platters to Degrade
During monsoon season (June–October), Dhaka humidity exceeds 85%. Condensation inside a hard drive's sealed casing causes read/write head friction and platter corrosion over time. SSDs are more humidity-resistant, but older spinning drives are especially vulnerable.
Ransomware Attacks Targeting Bangladesh Businesses
Ransomware incidents in Bangladesh rose sharply in 2024–2025. A ransomware attack encrypts all files and demands payment — often BDT 30,000–200,000 or more in Bitcoin. The only reliable defence is an offline backup that ransomware cannot reach.
Physical Drive Lifespan
Consumer hard drives have an average lifespan of 3–5 years under normal use. In Dhaka's heat and dust environment, drives in desktop PCs without regular cleaning can fail in 2–3 years. An external backup means a failed drive is a BDT 800 repair rather than a catastrophic loss.
Hard Drive Backup vs Cloud Backup — Which Is Better?
| Feature | External Hard Drive | Cloud Storage (Google Drive / OneDrive) |
|---|---|---|
| Speed | Very fast (USB 3.0: 100–150 MB/s) | Slow for large files (depends on internet) |
| Cost (one-time) | BDT 3,500–5,000 for 1 TB drive | Free 15 GB (Google); paid plans from BDT 170/month |
| Works offline | Yes — no internet needed | No |
| Protection from ransomware | Yes (if kept disconnected) | Partial (version history helps) |
| Protection from physical loss (fire, flood, theft) | No | Yes |
| Easy access from anywhere | No | Yes |
| Setup complexity | Low | Low to medium |
| BAYAS recommendation | First line of defence | Second layer — use both |
Best practice: use both. An external hard drive gives you a fast, local, offline copy. A cloud backup protects against physical disasters. BAYAS recommends the 3-2-1 rule: 3 copies, on 2 different media, with 1 offsite (cloud).
Step-by-Step: What BAYAS Does During a Data Backup Home Visit
- Assessment call (5 min): Before arriving, our technician asks about drive sizes, what needs backing up (everything vs specific folders), and your preferred destination.
- Arrival and setup (15 min): Technician arrives, connects external drive or checks cloud storage credentials.
- Drive inventory (10 min): We list all internal drives, partitions, and key folders — Documents, Desktop, Downloads, Pictures, Videos, Outlook/email data, accounting software data.
- Backup initiation (varies): Copy begins. Typical times: 250 GB = ~45 min via USB 3.0, 500 GB = ~90 min, 1 TB = ~3 hours.
- Integrity verification (20 min): We run a checksum comparison on a sample of critical files to confirm the copy is error-free.
- Restore test (10 min): We restore 3–5 random files from the backup to confirm the backup is actually readable and complete.
- Documentation: We provide a simple backup inventory — a text file listing what was backed up, when, and where.
- Automation setup (optional): We configure Windows Backup, Macrium Reflect Free, or cloud sync to run automatically going forward.
What Data Can BAYAS Back Up?
- Windows PCs: All user profile folders, installed software data, browser profiles (Chrome, Firefox, Edge), email clients (Outlook .pst files, Thunderbird profiles)
- Laptops (all brands): Same as above; we also back up ASUS, HP, Dell, Lenovo, Acer, and MacBook laptops
- Accounting and business software: Tally, QuickBooks, custom accounting databases (.mdb, .accdb, .sqlite files)
- Photography and creative work: Adobe Lightroom catalogs, Photoshop files (.psd), video footage (.mp4, .mov)
- Medical and legal: Patient records, case files — with confidentiality maintained by our certified technicians
- Old drives: We can connect your old HDD or SSD (2.5", 3.5", M.2) via USB enclosure and back it up before disposal

Frequently Asked Questions
How much does a data backup service cost in Dhaka?
BAYAS data backup service in Dhaka starts at BDT 1,500 for a basic drive copy (up to 250 GB) during a home visit. A full PC backup including all drives, cloud sync setup, and a restore test costs BDT 3,000. If you need us to supply a 1 TB external hard drive, the total package is BDT 4,500–6,000 depending on the drive brand. Travel is included across all 36 Dhaka zones.
Can BAYAS come to my home or office for a backup service?
Yes — BAYAS offers home and office data backup service across 36 Dhaka zones including Uttara, Gulshan, Dhanmondi, Mirpur, Banani, Bashundhara, Mohammadpur, and Old Dhaka. Call or WhatsApp 01712-644590 to book a same-day or next-day slot. We operate 8 AM–11 PM, seven days a week.
How long does a data backup take?
Backup time depends on the volume of data. Typical times with a USB 3.0 external drive: 250 GB takes around 45 minutes, 500 GB takes 60–90 minutes, 1 TB takes 2–3 hours. The technician stays on-site throughout to monitor the process and run an integrity check before leaving.
What is the safest backup method for a Dhaka home or business?
For Dhaka's environment, BAYAS recommends the 3-2-1 backup method: keep 3 copies of your data, on 2 different storage types (e.g., internal drive + external drive), with 1 copy offsite (cloud). This protects against power surges, drive failures, ransomware, and physical disasters like fire or flooding.
Can you back up a laptop before I send it for repair?
Yes — BAYAS always recommends a pre-repair backup. If you're bringing your laptop for screen replacement, motherboard repair, or any hardware fix, we can perform a backup first (BDT 1,500–2,000 depending on drive size). This is especially important for repairs that require a factory reset or Windows reinstallation.
Will my data be private during the backup process?
Yes. BAYAS technicians follow strict confidentiality practices. We do not open, read, or copy your personal files. Our role is to verify that the backup is structurally complete, not to examine content. For medical clinics, legal offices, and accounting firms, we can sign a non-disclosure agreement on request.
Can you set up automatic backups so I don't have to think about it?
Yes. BAYAS sets up automated backup schedules using Windows Backup (built-in, free), Macrium Reflect Free, or cloud sync (Google Drive, OneDrive, Dropbox). We configure it before leaving, test one automatic run, and explain how to verify the backup is running. Automation setup is BDT 1,500 added to any backup package.
What if my hard drive is already failing — can you still back it up?
If your drive is clicking, slow, or showing errors, act immediately. BAYAS technicians can attempt a precautionary backup from a failing drive using specialist tools (ddrescue for Linux-based recovery). Success rate depends on the degree of failure. This is classified as an emergency backup — pricing starts at BDT 3,000 and increases based on recovery complexity. For fully failed drives, see our Data Recovery Service Dhaka.
