Multi-threading support for Zip compression

Post by justinhow »

Most good Zip type compression tools (e.g. 7-Zip etc) allow for using multiple threads/cores when compressing data. This allows either much more compression in a given timeframe and/or much faster compression speed.
As I understand Backup4All only uses a single core for compressing data so it is a bit limited for todays CPU's with 8+ cores.
You have settings for mult-threaded support elsewhere within Backup4All Iand I think compression just cries out for it as well.
Using B4All (v9.8 build 725) on Windows Server 2019

Hi,

The multithreading option in Backup4all applies to upload process only and it can use multiple cores if necessarily.
I will add your request on our Wishlist, for multithreading while zipping the files.

Yes please! Multithreading should be added. Perhaps not only for zipping files, but overall. I was a bit disappointed to read that it was only added for uploading, where the release notes seemed to indicate that it was overall. Multithreading will likely speed-up the backup process greatly with modern computers. Backup4All currently lacks speed comparing to another backup program I use for imaging and backing up files and folders. That program takes 2h15m for a full backup including testing, where Backup4All takes 3h45m for the same backup. This is 66% longer. Therefore I currently only use Backup4All for cloud backups, which that other program cannot do.
