KBackup
Backup
A menu-bar app that keeps up to two folders backed up to OneDrive and never deletes anything.
What it does
KBackup lives in your menu bar and keeps a copy of up to two folders in your OneDrive. It copies in one direction, your folder to OneDrive, only what is new or changed, and nothing in OneDrive is ever removed.
It started as one person's drive-plus-OneDrive workflow, so it understands external drives: it syncs when a drive is connected, and it copes with OneDrive's naming rules instead of failing on them.
It never deletes anything from OneDrive, never changes your folder, and never replaces a newer file in OneDrive with an older one.
New and changed files are compared by size and date, written to a temporary file and swapped in when complete. Unplugging mid-sync cannot leave a half-copied file.
It backs up when a drive with a ticked folder is connected, once at login, and whenever you press Sync Now.
Names OneDrive cannot store, and file types it refuses, are skipped and listed with what OneDrive would have made of the name. Nothing is renamed.
Every sync is listed with the exact files copied. Click the magnifier to reveal one in Finder.
A menu-bar app that opens at login, skips hidden and system files, and runs next to ADVANCED without touching it.

FAQ
BASIC never deletes anything in OneDrive and never changes your folder. The only things it removes are its own temporary files.
OneDrive cannot store certain names (invisible characters, " * : < > ? \ | and trailing spaces), and an organisation's OneDrive may refuse some file types such as .bat, .jar and .pid. BASIC skips them and lists them in Activity with what OneDrive would have made of the name. Nothing is renamed.
BASIC backs up to OneDrive only. Other destinations, including a network drive or another disk, are an ADVANCED feature.
When a drive with a ticked folder is connected, once at login, and whenever you press Sync Now (Command-S).
No. KBackup copies files into the OneDrive folder that the OneDrive app keeps on your Mac, and OneDrive does the uploading. KHBROS never sees your files.
Up to two in BASIC. Unlimited folders are part of ADVANCED.
Yes. BASIC is free to download and use, with no time limit, no ads and no account. ADVANCED will be the paid edition when sales open.
