Backing up to the Cloud:full+ incremental vs. full+differential

Thread needs solution

I am going to be setting up backing up to the Cloud.

Full + differentials seems to be more secure than full + incrementals because with full+differentials one is only dependent on on differential plus the last full while with full+incrementals, one is dependent on all incrementals back to the last full.

Consider a full + 5 incrementals partition backup. If I want to recover everything that was on the PC when incremental 5 was created, if incremental 3 is corrupt, I lose. But if I have full+differential, and differential 3 is corrupt, I win.

Files on local backups do occasionally become corrupt, but in the Cloud they never do.

So for Cloud backup, the security of full + incrementals is the same as that of full + differentials. I am guaranteed to be able to recover from any full + incremental backup scheme, just as I can recover from any full + differential backup scheme.

So if I use Cloud backup, I might as well save space by doing full + incrementals.

Is my reasoning valid, or am I missing something?

Cloud backup works in a different way than incremental or differential.

Cloud backup performs an initial full backup of a disk, folder or file.  Based on the schedule you set for the backup each following backup is done as what is know as a Delta.  A Delta is simply any changes to the initial full backup are then backed up to the cloud.  So space/time saving is built in to the Cloud backup process.

When you back up your data to Acronis Cloud, the first backup may take a considerable amount of time to complete. Further backup processes will likely be much faster, because only changes to files will be transferred over the Internet.

Once an online backup is started, you are free to close Acronis True Image. The backup process will continue in background mode. If you suspend the backup, turn off your computer, or disconnect it from the Internet, the backup will resume when you click Back up now or when the Internet connection is restored. A backup interruption does not cause your data to be uploaded twice.

 

Please also take a look at this thread if you are planning to only use Cloud for backups.  I highly encourage you to have  a local backup first, and use Cloud for a secondary, offsite backup.
