Multi-threaded / Parallel version?
Posted: Thu Sep 10, 2015 11:21 am
I want to move away from Acronis TIH to be able to backup a Win/Linux triple boot machine. IFW seems to be excellent, apart from the dismal compression speed. I've tried all the compression types from SpeedA->Standard->SizeC (boot ISO and Win host) and would really like to use SizeB. But (and this is a show-stopper for me) looking at the task manager, I can see IFW is running the compression in as a 'single-threaded' process, for all compression types. Acronis uses all 8 'cores'. At the moment I'm using Acronis for NTFS and Clonezilla (which uses all cores) for ext4. I would really like to use a single program to do everything in one go (and can mount images for single file extraction).
What's holding me back from using IFW is the way higher backup time:
Proc: i7-4810MQ (4 physical cores at 3Ghz throughout the process)
Disk: Total 300Gb NTFS partitions (out of 480Gb SSD - 200Mb/sec sustained) containing mostly apps and virtual machine images:
Dest: 1TB external 7200rpm USB3 disk at 90Mb/sec sustained throughput.
Acronis on High compression: 0:50 hrs approx (using 8 'cores').
IFW on Enhanced SizeB : 2:20 hrs approx.
Both produce 180Gb approx target file.
It takes a LOT longer if I try to backup everything on the laptop (linux ext4 partition + 1TB NTFS spinning disk containing games). Clonezilla is twice as fast approx on ext4 compared to IFW (with similar target sizes) at the moment.
I realise that in the past, multicore was not so much an issue since most machines were dual cores throttled by the backup target disk/network. These days personal systems have gigabit LAN and SSDs, so multi-threaded apps processing large amounts of data makes a huge difference for more recent set-ups.
So, my question is:
will there be a Version3 of IFW/IFL which uses all available processing power?
(If so, I would buy the whole shebang in a heartbeat )
Arst.
