Turn File Vault off, select backup now from the Time Machine menu and see what happens. If you are in the middle of a large backup, just turn File Vault off to see if performance improves.
Some information on Time Machine and File Vault.

Hello!, Yup, the encryption process went all the way. I left the computer the time necesary for it to be complete. But then when starting the time machine on a 2.5" external drive (500 gb, 7200 rpm) that works perfectly, the time machine was taking forever.
I turned off the encryption and did the backup. It worked. My problem is, ¿doesn´t time machine work with filevault? Does it always take this long for a backup to happen?
