Doing the daily backup of my 12TB media data

How do you deal with this? Using 2 backed up hard drives isn't viable for me or most people since its too costly.

either back up specific content at a time minimizing the amount of unprotected data, or get more space

Use rsync, there's no need to recopy the whole directory if only one or two files changed, just copy the one or two modified files.
Also look into rsnapshot.

I don't see how this results from doing a backup. Why do you have to do that? Why don't you use a tool which syncs the backup with the live data without transferring data which already exists in the backup?

cwRsync which is for windows, It says you got to pay for it

Uh what the fuck?

Robocopy /s /e /xo

>not using cygwin
heh.

what does this do?

Hell, even use the build in backup system is better than what your doing. If you don't want to get into the other proposals in this thread, just use the build in tools in windows, OSX or whatever your using.

Can you use Rsync using the Windows Linux subsystem? Might be a free way...

>>have to delete the whole backup folder then copy over the data from the main drive
What the fuck?

Google robocopy and ctrl+f /s /e /xo.

dd if= of=/dev/

well I am trying it but those Robocopy File Classes hardly make sense. Exclude older won't copy over the source files to the destination if the source files is older than the destination one? Why would I want to do that?

Because you only want to copy things that have changed.

cp -r -u -p copies only files that do not exist or have been updated. If you use windows, install WSL or Cygwin to do this.

>Why would I want to do that?
When you don't want to overwrite files you have modified with older files?

Or FreeFileSync, which is free and open-source

I'm copying over the whole source to the destination, in the source file I've deleted files I no longer want, modified and made new files.

Use robocopy with appropriate flags if you are a Windows mouth breather

You probably want something more like rsync that'll do more intelligent update/copy/syncing.

I use rsync for that.

looks like only /MIR option was needed in robocopy, seemed to do the job. Mirrors the whole source to destination identical while skipping identical files.

Is this some bug? A lot of the times says pic related, when I check the files it literally mirrored the source to destination and I could see it copy over files while in progress.

Why? LTSC has WSL.

Then just use /mir

Make log file of the job with /log

SyncBack Free for Windows. Hardly gets enough credit.

/v/ here, how comes this thread has actual answers and discussion instead of having derailed into reddit reee'ing about anime and anime is for pedo slapfights based on the image in OP?

that happens all the time here too.

Because /v/ is literally full of children and spics now.
I can’t even go there anymore.

How the fuck do you end up with 12TB of data and not even know full, incrimental, and differential backups?

Pure autism. I backup monthly with Acronis True Image and disconnect the backup hard drive once it's done. Also, it's an incremental backup, so it's pretty quick.

Man what the fuck is wrong with Windows users

Just stop hoarding kiddy porn, pal. Problem solved.

I keep telling myself that I'm going to setup a back system eventually but I also want to wait until I've organized my files how I want them.
How do I deal with this? Just backup the clusterfuck and organize later?
