Backup mac to synology time machine smb
Copy the sparsebundle to the network share root.Just make sure you have read/write permissions set on whichever SMB/AFP share you're going to dump this to. Create and set permissions on your network share.hdiutil does have a -resize option if you need to utilize that later. However, you can also specify a smaller size if you (like me) want to create a hard limit for the amount of space your Time Machine backups will take on your network drive. The -size parameter can probably be as large as you want, now that Apple has evidently fixed the sparsebundle issues that were causing all but the most recent backup to be dumped. So if your Mac is named MyMac, and the Network System Preferences panel lists your Ethernet ID as 00:18:b3:11:84:dd, then you would use MyMac_0018b31184dd for the name of the sparsebundle. Hdiutil create -library SPUD -size $SIZESPEC -fs Journaled HFS+ -type SPARSEBUNDLE -volname $MACHINENAME_$MAC_ADDRESS.sparsebundleWhere $SIZESPEC is the size of the backup volume, and $MACHINENAME_$MAC_ADRESS is your Mac's name followed by an underscore and then your Mac's MAC Address (otherwise known as its Ethernet ID visible in the Network System Preferences panel), but without the colons.
