I have an external hard drive where my Time Machine backups are located. My OS is El Capitan.
I would like to permanently archive this entire TM backup and move it to another hard drive, and it would be best to archive these backups to a compressed disk image.
I have tried to archive the
Backups.backupdb folder with SuperDuper! and Carbon Copy Cloner. CCC copies files to DMG but
Backups.backupdb is only 161 GB in size, and CCC has supposedly copied 190 GB, which has me thinking something is wrong.
I have not yet tried to create a ZIP archive or a DMG (using Disk Utility).
How can I create a DMG to archive
Backups.backupdb to another hard drive?
Thanks for help.
I tried to make DMG using Disk Utility.
After 6 hours, Disk Utility got error: Operation failed with status 2.
Creating "TM BU" dialog, "hide details" window was empty during 6 hours.
I used read/write format because i'm planning to index DMG with Spotlight after DMG is created if that's possible.
sudo mdutil -i on '/Volumes/TM BU' user name "name" password "password" with administrator privileges
Then if possible convert read/write DMG to compressed.
