little time advantage to differential backup

Help - CB
#1

I do a full backup of “user” every month and differential backups every week. I’m running an external 2Tb drive on a USB3 connection.

The full backup generally takes about 3 hours and takes about 300Gb of disk. A differential backup takes about 2 1/2 to 2 3/4 hour and produces a file about 2.5Gb. (So it’s really a smaller group of files that’s backed up.)

A partition backup also takes about 3 hours.

Given all of this, I’m trying to figure out the best kinds of backup to do. If everything is always going to take almost 3 hours, I might just as well do partition backups every week. But that seems kind of crazy.

Hi

We improved speed for incremental/differential files & directories backups in 4.0 version.
You can try it here.

Partition backups may take the same amount of time as before.

Thanks

Thanks for the information.

When you say speeded up, do you mean that 2 1/2 hours will go to 2 1/4 hour? Or go down to 1 1/2 hour? One is interesting. The other is not.

Also, is there any notion of when v4 will go gold (official release, out of beta)?

I would say it would go to 1/2 hour if less than 10% of data was changed.

It could be one or two months.

Thanks

Thanks. That’s great.
