Hello,

My Win2003 R2 domain server showing high cpu use. When I started domain backup. It was taking whole 2 days for just 280 GB data. Few day ago it was taking only 5 Hrs. Please help me in this regards,

Brief follow-up and practical checklist after the troubleshooting noted by (and the general server-behavior point from ). Focus on confirming the true bottleneck, preventing recurrence, and keeping backups efficient without repeating earlier thread details.

Recommended immediate diagnostics

  • Capture a short PerfMon trace during a backup window. Key counters: Processor(_Total)\% Processor Time, Process(<backup exe>)\% Processor Time, System\Processor Queue Length, LogicalDisk(_Total)\Avg. Disk Queue Length, PhysicalDisk(_Total)\Avg. Disk sec/Read and /Write, Network Interface\Bytes Total/sec, and Memory\Available MBytes. ABLG or CSV output helps later analysis.
  • Use Process Explorer to identify the top CPU threads, note the owning process, path and loaded modules. A thread call stack often shows whether CPU is kernel, driver, or user-mode.
  • Isolate components: run a controlled backup to a local disk (no network, no compression) to separate CPU vs network vs storage issues.
  • Review backup software settings: compression, encryption and multithreading raise CPU load. Temporarily disable compression to measure impact.
  • Inspect storage and drivers: check RAID controller firmware, NIC drivers, SMART logs and SAN pathing for transient I/O waits that look like CPU problems.

Post‑cleanup hardening and operational tips

  • Configure antivirus exclusions for backup target folders and the backup process temporary files to avoid double-scanning during jobs.
  • Run an offline full-scan/rootkit check from clean media after any compromise, verify system files and autoruns (Sysinternals tools are useful).
  • Because Windows Server 2003 is long past mainstream support, plan migration or strict isolation; unsupported hosts remain at greater risk and complicate long-term stability.

Yes it is really some high in WIN2003. i think it is because of some difference from other windows OS.

First of all thanks for the replay.

I found the the problem. My norton which is running on this server has not detetected some viruses. But when I have scan all the drive for another system I found some torgen virus on one of drive on the server. Thankfully it has removed it & now my server cpu use is just 8 to 20% while backup is running. Although I still observing the speed. Thanks any way for the replya once again.
