Re: Old IFW V2.x slows down dramatically during backup

I absolutely will. It's about 3.5 hours later, and the ETA has barely changed. The backup has slowed to about 20Mb/s at this point. It's at 53%.

SSD getting backed up. The last I knew, we're not supposed to defrag.TeraByte Support wrote: ↑Sun Jul 03, 2022 3:16 pm The program itself doesn't slow down, in addition to the other potential fragmentation or OS resource/driver type issue, antivirus scanning the data and the type of data (such as data that won't compress - especially if not using the Enhanced Speed A option) as well as the hardware itself due to heat built up (ensure system fans working and system clean) or the drive accessing the data. You can also enable VSS or adjust PHYLock throttling (you should leave priority at normal).
Have you tried the default comp of Enhanced Speed A ?I'm using maximum compression since CPU usage is so minimal.
How about with the hash file. Do you use "direct" or "os" to save the file?I repeated the backup using IFL. No hashes. Image size is the same and backup time was 3:32. That is fast.
On the machine with the 2TB and 1TB M.2 NVMe drives (the main one we're discussing here), when using V2 I found no speed difference between /comp:14 and /comp:10. I have not tested this yet in V3.TeraByte Support wrote: ↑Mon Jul 04, 2022 4:05 pm Have you tried the default comp of Enhanced Speed A ?
That's Brian K, not me. I don't use Linux here.How about with the hash file. Do you use "direct" or "os" to save the file?
