Force a final Backblaze backup
Open the Backblaze preference pane, click Backup Now, and wait for Remaining Files to hit zero. This guarantees your Backblaze cloud copy is current before you change anything else, so the 30-day retention clock after cancellation starts from a known-good state.
Decide if you need a point-in-time archive
If you want a full local copy of what Backblaze has before you cancel, order a Restore by Mail hard drive from the Backblaze website or queue a ZIP download from the restore page. Both take time, so start this now if you want it. If you are happy to let the current live files serve as your archive, skip this step.
Install macup and set your recovery key
Download the DMG from macup.app, drag macup into Applications, and launch it. Sign in, then follow the recovery-setup wizard: create a passphrase, download the recovery code, and store it somewhere outside this Mac. Files are AES-256 encrypted on-device with keys wrapped by that passphrase, so the recovery code is the only reset path.
Pick a destination
Open Destinations in the menubar app and add one. macup Cloud is the managed tier with ransomware-resistant Object Lock and no egress fees, which makes it a clean swap for Backblaze Personal. BYOS points at an S3-compatible bucket, a NAS, or an external drive for five dollars per month per device. You can run up to three destinations at once for a belt-and-braces setup.
Recreate your Backblaze backup scope
Backblaze Personal backs up every attached drive by default, minus its exclusion list. Create a macup backup set called Everything and include your home folder plus any external drives you want protected. Open the Backblaze preference pane, switch to Exclusions, and copy each pattern into the macup set's Exclusions tab so you do not re-capture caches and scratch files.
Run both tools in parallel for 30 days
Leave Backblaze running. Let macup run continuously alongside it. Thirty days lines up with Backblaze's post-cancellation retention window, so if anything goes wrong in the first month you still have both safety nets.
Verify with a test restore
Pick a file whose contents you know exactly, open Restore in the macup dashboard, find it, and restore to a scratch folder on your Desktop. Compare against the live file with Get Info or a checksum. Do this before you cancel Backblaze, not after.
Cancel Backblaze and reclaim the spend
Once the parallel period is up and the test restore passed, sign in to the Backblaze website and cancel your subscription. Your data remains accessible there for 30 days, so download anything else you want in that window. After day 30, Backblaze deletes the archive and macup is your sole cloud copy.

Known gotchas

Things to watch for.

Specific to migrating from Backblaze — small issues that trip most people up.

Backblaze's 30-day window is shorter than it feels

The 30 days after cancellation cover access to existing files, not new backups. If you cancel and then realise on day 25 you need a deep version history, you are restoring against a frozen copy that has not been updated since the cancellation date.

External drives have to be attached to be backed up

Backblaze Personal quietly deletes a drive's cloud copy after 30 days of it being unplugged. macup will also stop capturing an unmounted drive, but will hold existing snapshots under your retention policy. If you have a drive you rotate in and out, flag its backup set Only When Mounted and plug it in at least once a month.

Large initial upload can take weeks

A first-time upload of several hundred gigabytes to any cloud destination is bounded by your upload bandwidth, not the destination. Schedule the initial seed on a wired connection if you can, and leave the Mac awake. macup resumes cleanly across sleeps and network blips, but the total wall-clock time does not change.

The recovery code is the only way back in

macup cannot reset your passphrase for you. Print the recovery code or save it in your password manager before the first snapshot finishes uploading.
