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

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.
Do you know you can monitor your backups remotely with Backup4all Monitor? You can read more here:
