Synology NAS Troubleshooting for Small Businesses in Singapore
A Synology NAS (Network Attached Storage) is one of the most practical tools a small business can run — shared file access, centralised backups, and a single place for your team’s data. When it stops working, the impact is immediate. Staff cannot reach the files they need, backup jobs go silent, and nobody is quite sure what happened or how serious it is.
This page covers the common Synology NAS issues we see in Singapore small business environments, what we can help with, and when the problem may require specialist data recovery services instead.
Common Synology NAS Issues in Singapore Small Offices
Shared Folders Not Accessible on the Network
This is the most frequent issue. Staff open Windows Explorer or macOS Finder and the mapped drive is missing, or the NAS shows up but access is denied. Common causes include a DHCP IP address change after a router restart, SMB protocol version mismatches following a Windows update, or user permission changes inside DSM.
NAS Not Appearing After an Office Move or Network Change
Moving to a new office or changing your router often breaks the NAS network configuration. The device may be online but unreachable because its static IP conflicts with the new network range, or the workgroup settings no longer match the office PCs.
Backup Jobs Showing Errors or Running Silent
Synology’s backup tools — including Hyper Backup and Active Backup for Business — can fail quietly. Jobs show a warning in the notification log but nobody receives the alert. Common causes include destination storage being full, backup tasks that have not been updated after a DSM upgrade, and cloud destination credential expiry.
Drive Warning Alerts or Degraded Volume Status
DSM will flag a degraded RAID or a drive health warning in the storage manager. This requires prompt attention to understand whether a drive needs replacement and whether data integrity is at risk. The appropriate response depends on the RAID type and how many drives are affected.
Slow File Access or Transfer Speeds
Slow NAS performance in a small office is usually a network issue rather than a hardware issue. Common causes include a 100Mbps switch port instead of Gigabit, a faulty cable, or excessive simultaneous access from mapped drives on multiple PCs.
User Access and Permission Issues
Staff getting access denied on folders they should be able to reach, or users with access to folders they should not see. These are DSM user and shared folder permission configuration issues.
DSM Update or Login Issues
After a DSM version update, some services may behave differently or require reconfiguration. Occasional login lockouts occur due to failed authentication attempts triggering auto-block in DSM security settings.

Frequently Asked Questions (FAQ)
Why is my Synology NAS not showing up on the network? The most common cause is a changed IP address after a router restart. Other causes include a Windows update that altered SMB settings, or the NAS and PCs being on different network segments. A basic network check usually identifies which applies.
Can you recover data from a failed Synology NAS drive? We can assess the situation and advise on the condition of the volume. Physical data recovery from failed drives requires specialist equipment we do not operate. If data recovery is needed, we will advise accordingly.
Do I need to be on a monthly contract for NAS troubleshooting? No. NAS troubleshooting is available as a one-off service with no ongoing commitment required.
How long does it take to fix a Synology NAS issue? Most network access and permission issues are resolved within a single visit. More complex issues involving backup reconfiguration or RAID assessment may require a follow-up visit. We do not provide time estimates before understanding the specific situation.
Can you help set up Synology NAS backup for my business? Yes. We help configure Hyper Backup and Active Backup for Business (selected models), including backup to external drives, local network destinations, and cloud storage. We also verify that backup jobs are running and that alerts are reaching the right person.
What Synology models do you support? We work with Synology DiskStation (DS) models commonly used in small office environments. We do not support non-official hardware
My NAS backup has been failing silently. How do I know if my data is safe? A silent backup failure means your backup jobs ran without completing and no alert was sent. This is a configuration issue, not necessarily a data loss event. We can review your backup task history in DSM and confirm the last successful backup date before reconfiguring.
One-Off Service — No Contract Required
NAS troubleshooting is available as a standalone service for Singapore small businesses. No monthly commitment, no retainer.
If your issue turns out to be part of a wider IT problem — network configuration, device management, or ongoing backup reliability — we will assess the full scope and advise on costs accordingly before any additional work begins.
