Hello @Adrienloyat and welcome to the forum!
Database Recreate can, unfortunately, take awhile, especially for huge backups (which yours is not IMO). Probably the best thing to do to see what’s happening is to use About --> Show log --> Live --> Profiling to observe activity. There are some cases (and an identified bug) that cause heavy downloads. Alternatively, database writes can be the bottleneck. It’s hard to say without measurement, so just check for progress… Fortunately I believe this code is getting rewritten, so perhaps it will be in good shape by next beta release.
