Backup & Disaster Recovery in Westchester County, NY

Westchester businesses spread their systems across a head office, a branch or a warehouse, and a workforce that commutes some days and works from home the rest, which means an outage in one place reaches all of them. Storms, multi-day power failures and ransomware are the usual causes. NetSys provides backup and disaster recovery across the county on the corridor our engineers already drive between Brooklyn and the Hudson Valley: immutable backups, restores tested and timed, recovery objectives per system, ransomware recovery, continuity planning and Microsoft 365 backup, month to month.

The short answer

NetSys delivers backup and disaster recovery to businesses across Westchester County, from Yonkers and New Rochelle through White Plains to the northern towns. The service includes immutable backups with offline and off-site copies, cloud replicas for the systems a firm cannot trade, treat or bill without, recovery time and recovery point objectives agreed per system, restore tests run on a schedule and timed, ransomware recovery from isolation through root cause, business continuity planning for a hybrid workforce and multiple locations, and independent Microsoft 365 backup. Westchester sits inside our on-site coverage between the Brooklyn headquarters and the lower Hudson Valley, so recovery visits are routine scheduling. Our only office is in Brooklyn, and every agreement runs month to month, with a dedicated account manager on a real cell number.

Disaster recovery risk in Westchester County

Westchester's outages come from the weather as often as from attackers. Nor'easters and summer storms take down power for days in the northern part of the county, and a head office in an office park depends on building systems it does not control. The business shapes here compound the problem: a wealth management firm whose advisers work from home on client systems that live on a server in White Plains, a medical group with several offices and one practice-management server, a fitness or retail chain whose point-of-sale data sits at each site, a distributor with an office in one town and a warehouse in another. Ransomware crews target the firms that move money and see patients. Regulators have expectations in writing: NYDFS Part 500 requires continuity and recovery plans for insurance agencies and other licensed businesses, SEC examiners ask advisers for theirs, and HIPAA requires a contingency plan. Insurers ask everyone for offline copies and a tested restore.

How backup and disaster recovery reach Westchester County

An engineer visits the head office and each branch to inventory what runs where, then we agree the recovery objectives with the people who depend on each system: client systems within hours, point-of-sale by the next opening, email the same day. Backups are rebuilt to meet them: immutable copies that cannot be altered from inside the network, an offline copy, off-site replication, cloud replicas for the systems that must return fast, and cloud-to-cloud backup for Microsoft 365. Restores are tested and timed on a schedule. The continuity plan is written for the way the county works, with staff continuing from home on current data when the office is dark and locations covering for each other. Westchester lies on the corridor between our Brooklyn office and the Hudson Valley, so rebuilds and recovery visits are routine. Terms are month to month.

Who backup and disaster recovery in Westchester fit

Registered investment advisers and wealth managers who will be asked for a continuity plan at their next exam, insurance agencies under NYDFS, medical and dental groups with a HIPAA contingency obligation, law and accounting firms whose document systems are the practice, multi-location fitness and retail operators, and distributors with an office and a warehouse in different towns. Firms with a hybrid workforce fit especially well, because the plan turns working from home into the recovery strategy rather than an accident. A firm with an internal IT person fits as co-managed, with NetSys owning the backup platform, the tests and the runbook. A firm that cannot say how long recovery takes today is the firm the first restore test is for.

What is included

Backup & Disaster Recovery in Westchester County, NY: what NetSys delivers

Backups across locations

  • Immutable backups of servers and cloud workloads at the head office and every branch
  • Offline and off-site copies so one building's flood, fire or outage is never the only version
  • Cloud replicas for client, clinical and point-of-sale systems that must return fast
  • Mailboxes, OneDrive and SharePoint backed up outside Microsoft's own retention
  • Daily verification of every backup job, with failures investigated the same day

Recovery objectives and testing

  • Recovery time and recovery point objectives agreed per system with the people who depend on it
  • Restore tests timed on a schedule and written up for partners, examiners and insurers
  • A runbook that names the order of recovery and who does each step at each location
  • Plan reviews when a site opens, a system moves to the cloud or the business changes

Ransomware recovery

  • Isolation of the affected site or devices without taking the other locations down
  • Recovery from immutable copies in the order the business needs
  • Root cause identified and closed before anything is restored
  • An incident timeline written for regulators, counsel and the insurer

Continuity for a hybrid, multi-site business

  • Staff working from home on current data when the office loses power or access
  • Locations covering for each other, with phones redirected and clients or members moved
  • Manual procedures for trading instructions, patient intake or point-of-sale during an outage
  • Communication paths that survive the loss of the office network and phone system
Illustrative engagement

A Westchester wealth management firm with a server in an office park

A composite example of work we do in Westchester County, NY, written so you can picture the first 90 days. It is not a specific client. Our real, anonymized engagements are in case studies.

A registered investment adviser with a small staff, client systems on a server in a White Plains office park, advisers who work from home two days a week, and a backup to a cloud service that was set up years ago and never restored from. A winter storm left the office park without power for most of a week, and the firm found that advisers could not reach client records from home. The compliance consultant wants a written business continuity plan before the next exam.

  • Inventory and recovery objectives agreed with the partners: client systems and email within hours, historical documents within a day
  • Immutable, off-site backups of the server with an offline copy, and the old cloud backup verified with a real restore before it is retired or kept
  • A cloud replica of the client systems so advisers can work from home on current data when the office park is dark
  • Independent Microsoft 365 backup with retention set to the firm's record-keeping requirements
  • A timed restore test, a runbook, and a written business continuity plan assembled for the compliance consultant and the examiner

The next power outage in the office park moves the firm to home offices on current data rather than to voicemail. The examiner receives a continuity plan that describes tested procedures, and the partners know the recovery time because they watched the test. An engineer on the corridor handles the hardware. The agreement is month to month.

Common Questions

Backup & Disaster Recovery in Westchester County, NY: FAQs

Who provides backup and disaster recovery in Westchester County?

The NetSys Group provides backup and disaster recovery across Westchester County, which sits inside the on-site corridor our engineers drive between the Brooklyn headquarters and the Hudson Valley. The service includes immutable backups with offline and off-site copies, cloud replicas for critical systems, restores tested and timed, recovery objectives per system, ransomware recovery, business continuity planning for hybrid and multi-site firms, and independent Microsoft 365 backup. Agreements run month to month, and NetSys has served business clients since 1998.

Do you come on-site in Westchester for recovery work?

Yes. The county lies between our Brooklyn office and the lower Hudson Valley coverage area, so inventory visits, server rebuilds and recovery work in White Plains, Yonkers, New Rochelle or the northern towns are routine scheduling. Our main line, 845-203-3914, is a Hudson Valley number, and the company's only office is in Brooklyn. Backup monitoring, restore tests and most recovery steps run remotely, and engineers come when hands are needed at the rack.

What do investment advisers and insurance agencies in Westchester need for business continuity?

NYDFS Part 500 requires covered insurance agencies and other licensed businesses to maintain written business continuity and disaster recovery plans, test them, and keep backups adequate to restore operations. SEC examiners ask registered advisers for their continuity plans and expect to see them tested. In both cases the plan has to describe real controls: immutable backups, a recovery runbook, a tested restore and a way for staff to keep serving clients when the office is unavailable. NetSys builds and documents each piece.

Can staff keep working from home if the Westchester office loses power for days?

Yes, if the systems were designed for it before the storm. Cloud replicas of the client, clinical or accounting systems, independent Microsoft 365 backup, and remote access staff have used before the emergency let a firm continue from home offices on current data. The continuity plan says how phones are redirected, how clients are reached and which tasks proceed manually. We rehearse it, because the first power outage should not be the first time anyone reads the plan.

How do you handle backup and recovery for a business with several Westchester locations?

Every location is inventoried and gets its own recovery objectives, since a branch that only needs point-of-sale back by the next opening is different from a head office running the accounting. Backups at each site are immutable, with off-site copies so no single building holds the only version, and cloud replicas cover the systems every site depends on. The runbook names who does what at each location, and the continuity plan has sites covering for each other.

How long does ransomware recovery take for a Westchester business?

With a plan built beforehand, a business is usually working again within a day. NetSys has handled more than thirty ransomware incidents in the past three years and fully recovered every one; the clients who had a disaster recovery plan in place were back within 24 hours. The recovery follows the runbook: isolate the affected devices, restore from immutable copies in priority order, close the entry point, and bring systems back with an engineer verifying each step.

Backups are only real once restored
