Cum câștigi spațiu pe Windows Server folosind Data Deduplication

Dacă administrezi un File Server, știi că utilizatorii tind să salveze același fișier în zece locuri diferite. În loc să cumperi hard disk-uri noi, poți activa Data Deduplication, o funcție nativă care analizează blocurile de date și stochează o singură copie a segmentelor care se repetă.

Condiții de bază

  • Funcționează pe volume formatate NTFS (sau ReFS în versiunile mai noi)

  • Nu se recomandă pe volumul de sistem (C:\)

  • Este ideal pentru: File Servers (economii de ~30-50%) și Virtualization Libraries (~80-90%).

Cum activezi și configurezi DNS-over-HTTPS (DoH) în Windows 11

Fără DoH, interogările DNS sunt trimise în text clar pe portul 53, fiind vizibile oricui poate inspecta traficul de rețea. Astfel, furnizorul de internet (ISP), administratorii de rețea sau atacatorii pot vedea ce site-uri vizitezi.Cu DNS over HTTPS (DoH), comunicațiile dintre computerul tău și un server DNS compatibil DoH sunt criptate.

Nimeni nu poate intercepta cererile DNS pentru a monitoriza adresele pe care le vizitezi sau pentru a falsifica răspunsurile serverului DNS. Windows 11 include suport nativ pentru DNS-over-HTTPS (DoH), permițându-ți să criptezi interogările DNS fără a instala software terț.
