I recently had a critical drive failure on my network drive that I use for Time Machine backups. Creating the first backup over the network (with ~1TB of data) will be painfully slow.
I've already created a backup using Time Machine on the drive mounted via USB, however this is a Backups.backupdb
folder structure, not a backupbundle
disk image that Time Machine uses when working over the network.
Is there a way to create/convert a new backupbundle
file with the Backups.backupdb
folder such that I don't have to run a first full backup over the network? Alternatively, is there a way to convince Time Machine to use the backupbundle
structure when backing up over USB?

While I haven't tried this personally, I recently came across a workaround posted on the MacRumors forums that claims it should work:
Another variation on this method creates a local Samba file share mount on the USB drive as a workaround. Full details in the linked answer, but a summary snippet follows:
If there is a simpler/more direct way to do it though, that would be awesome to know! I was thinking maybe something in the
tmutil
command line program may be able to do it, but haven't yet tried.According to Apple's Disk Utility User Guide, it appears possible to manually create a sparsebundle disk image:
Edit Note: macOS Catalina appears to use the extension
backupbundle
instead ofsparsebundle
, but it seems that this file is still mountable in the same ways as previously.
