[In my opinion] you may be using your backups in the wrong order.
Time machine works quietly and automatically in the background, without interrupting your regular work, and only saves the incremental changes (after the first full backup). Time machine backs up your machine — including every connected drive that is in a Mac compatible format. it can not back up Windows format drives.
Time Machine's "claim to fame" is that it is the backup that gets done. It does not ruin performance of the rest of the computer while doing its backup operations. You do not have to set aside a "Special Time" when you only do backups. When you need it, your Time machine Backup is much more likely to be there.
But wait, there's more:
Time Machine saves, and can re-create, ANY Moment in time for which it still holds backup files.
Example: a user posted that they had installed software that messed up their files. it was installed mid last week. They had done an ordinary restore to recover, but that restored to yesterday, and the problem was still there.
Readers were able to guide them to Time Machine.APP (not to be confused with Time machine preferences). This allowed them to look at the state of the major folder involved, back in time through each previous backup, until right BEFORE the bad software was added -- mid last week-- and restore as of that moment. They were thrilled.
