I have 6.8TB of Media I would like to backup. I have an extra external hard drive 7.3TB. Is there a way to make a space efficient incremental backup? I will be adding media and would like to be able to create a weekly backup of this.
Will it be a smaller backup if I just duplicity? Create an image? Mind you the 6.8TB is part of a 13TB Vg. I just want to be able to check for changes, if there are changes to make a backup, remove the previous backup, and do it on a weekly basis.
I would also like to be able to restore from this if I have any HDD failures. Would a LVM snapshot be able to handle this?
Thank you in advance for any assistance or advice.
