Please do not put direct links to apk files, rather put a link to a reliable source from which to download the apk (f-droid, git repository, official site).
I see that it is a link to the izzyondroid repo, so I personally consider it safe, however it would be better to put the link to the app details rather than the direct download: DataBackup - IzzyOnDroid F-Droid Repository
I use Google account for some of my data but that’s interchangeable with alternatives.
phone logs, and messages: SMS Backup+ push those to Google Mail “folder”
My App List saves the list of all installed apps and then allows to quickly install the apps on the new phone. Supports both F-Droid and Aurora Store/Play Store. The alternative is to carry apks together with backup data.
Backup/restore with oandbackup (for legacy phones) or NeoBackup (much improved)
No need of the Titanium Backup and other proprietary stuff.
