NexusSec specifies, deploys and supports TrueNAS and Synology storage for businesses across India — ZFS pool design, DSM configuration, snapshot and replication strategy, and backup architecture that is actually tested. Storage is the one area where mistakes are permanent, so we design for integrity and recovery first.
Choosing the platform
Synology is an appliance: vendor hardware running DSM, with an excellent bundled software suite including Active Backup for Business and Hyper Backup. It is the pragmatic choice when you want storage to be a solved problem with minimal administration.
TrueNAS is free software built around ZFS, running on hardware you choose. Its advantage is data integrity — ZFS checksums every block and can self-heal detected corruption in a redundant pool. It is the right choice when integrity is a stated requirement and you have the skills to run it.
Full comparison: TrueNAS vs Synology.
What our deployment includes
| Area | What we do |
|---|
| Sizing | Capacity planning with realistic growth, not just today's data volume |
| Pool design | ZFS vdev layout chosen for your resilience and performance needs — this cannot easily be changed later |
| Memory | ECC recommended for TrueNAS, because ZFS protects data on disk and ECC protects it in memory |
| Shares & permissions | SMB/NFS configuration with directory integration and least-privilege access |
| Snapshots | Schedules and retention giving you rapid recovery from deletion or ransomware |
| Replication | To a second system or offsite, so a single-site event is survivable |
| Backup integration | Endpoint and server backup, with restores verified rather than assumed |
| Network & hardening | Segmentation, management isolation, updates — storage belongs in a restricted zone |
RAID is not backup. Neither ZFS nor Synology SHR protects you from deletion, ransomware, fire or theft. You need a separate copy, ideally offsite or immutable, and you need to have restored from it. We design to the 3-2-1 principle: three copies, two media types, one offsite — with immutability where ransomware risk warrants it.
The combination we often recommend
For business deployments we frequently pair the two: a Synology for user-facing shares and endpoint backup, where DSM's software suite genuinely earns its cost, and a TrueNAS system as the ZFS-based replication target. That gives convenience at the edge and integrity assurance for the copy that matters most.
Protecting storage from ransomware
- Isolate storage and backup networks from user segments — see segmentation
- Immutable or offline copies that ransomware cannot encrypt or delete
- Separate credentials for backup systems, never domain admin
- Frequent snapshots with sufficient retention to recover from delayed detection
- Tested restores on a defined schedule
Frequently asked questions
Should we choose TrueNAS or Synology?
Synology suits businesses wanting an appliance that works out of the box with excellent bundled backup software and single-vendor support. TrueNAS suits those who need ZFS data integrity, want to choose their own hardware and drives, and have the technical capability to run it. Many businesses benefit from both, using Synology for shares and TrueNAS as a replication target.
Do we need ECC memory for TrueNAS?
It is strongly recommended. ZFS protects data written to disk through checksums and self-healing, while ECC memory protects data while it is held in RAM before being written. If data integrity is your reason for choosing TrueNAS, ECC completes that protection and the additional cost is modest.
Is RAID a backup?
No. RAID and ZFS redundancy protect against drive failure only. They do not protect against accidental deletion, ransomware encryption, application-level corruption, theft or fire. You need a separate backup copy, ideally offsite or immutable, and you must test restoring from it regularly.
How do we protect our NAS from ransomware?
Isolate storage and backup systems on their own network segment away from user devices, use separate credentials that are not domain administrator, maintain immutable or offline copies that cannot be encrypted, take frequent snapshots with sufficient retention, and test restores on a schedule. Ransomware operators specifically target backups first.
Can you migrate our existing file server to a NAS?
Yes. We plan migrations to preserve permissions and structure, run the new system in parallel where possible, and cut over in an agreed window. Permission mapping between an existing file server and a new platform is usually the most delicate part, and we test it before cutover rather than after.
