Backup Lag

[rodionzissou]

I'm running a m4 256GB in the main bay and a 300GB HDD in the optibay. I set the HDD as my Time Machine's backup destination. I just started my first backup and it's quoting a seriously long time to complete. I've done a similarly sized backup to my external HDD using this same internal HDD, but in the main bay, and it only took an hour+ . What gives?

How long does it really take?
Did you try Black Magic speed test to test the HDD?
If that drive is slow, perhaps try a different one... could be HDD model specific. Could be bad HDD too...

black magic says it reads and writes at about 85MBps.

So, that's fine... not a hardware/driver problem. Back to first question... how long does it really take?

I haven't let it finish, The time remaining inched up to a day or so after letting it run for about half an hour so I just cancelled it. I followed this http://icomputerdenver.com/ssd-optimization-for-mac-os/ to relocate user folder to HDD as well as prevent hibernation for the SSD. Would this affect things? Those are the only two tweaks I made from the aforementioned guide.

Very strange, I just started again, (third attempt) to answer your question about how long it actually takes, and this is what it's reporting now. :S In dunno....weird.

Is your SSD super small, that you felt you needed to relocate user files???
I'm hearing bad things about relocating user files, so I would avoid it unless you really feel it necessary.

My reasoning for relocating user files was to reduce reads and writes to SSD (lengthen lifespan), because sometimes I read and write up to 20GB/day. I followed the above guide and haven't experienced any issues aside from this thread's subject, but all seems to be magically working now. I was running illustrator and VLC while trying to backup last night, they may have been why it was moving so slow?

I just use the separate device explicitly and add folders to the side-bar to make them easy to access in finder.

Could be...
