Backup of softwares or data is very essential nowadays and most of the times it is a very complicated process and may need a professional assistance. Gone are the days where backups were made in tape drives, floppy, CD or DVD. I believe Apple is the only operating system that comes with an efficient backup utility which is very handy. Apple OS X 10.5 provides a simple and powerful utility called Time Machine. What makes time Machine different from other backup applications is that it not only keeps a spare copy of every file, it remembers how your system looked on a given day — so you can revisit your Mac as it appeared in the past. All you need is just connect an external hard-drive and use

the Time machine. Now Apple came with up a wifi solution called Time Capsule which is a blend of WIFI router and external Hard disk drive. The device supports in either 500 GB or 1 TB sizes. Time capsule’s primary functionality is to backup data using WIFI and in case if a file is lost once can do a WIFI search and restore the file.

Time Capsule is a full-featured Wi-Fi base station that supports 802.11n along with regular Airport Extreme (802.11A,802.11b, 802.11g) standards including MAC address filtering delivering up to 5 times higher performance.

Additional features include:

• dual-band antennas for 2.4 GHz or 5 GHz frequencies;
• three Gigabit LAN ports;
• one Gigabit Ethernet WAN port;
• one USB 2.0 port for scanner, external hdd, and printer access.
• Wi-Fi Protected Access (WPA/WPA-2), 128-bit WEP encryption; and
• a built-in NAT firewall supporting NAT-PMP for features like Back to My Mac.
