Alternatives on How to backup Xperias
Hello @pter,
Welcome to the community!
As @uliwooly mentioned PC Companion is no longer supported, it has been replaced with Xperia Companion.
By "flushing" your device, do you mean reinstalling and/or resetting your device? If that is the case, a software repair using Xperia Companion might be what you are looking for. Otherwise a factory reset can be performed by going to Settings > Backup & reset > Factory data reset.
Let me know if there's anything else!
