You'd need to install something like 7zip to extract the tarball, and it'd take a long time, but you could do it.
How long are we talking? For ~200+ GBs, hours, days? My window machine is a core2 duo e8600 running at 3.33 GHz with 3.25 GB RAM.

Except it doesn't look quite so easy now since your system can't understand XFS. You'd have to reformat the drive as something else,
I think the drive comes XFS base, reformatting to another format shouldn't be too difficult. What would you suggest, NTFS? Based upon the output of the $ cat /proc/filesystems command, the system doesn't support NTFS either. Would NTFS still allow the tarball to be read by windows in a pinch?

or install XFS drivers. It's possible you already have them, just haven't loaded them yet -- try modprobe xfs.
Does this command just see if they are there or load them if they are? Is this safe, stability wise? I don't want to make changes that jeopardize the safety of the data prior to having it backed up...

Quote:
(The offline backup doesn't care what's on the USB drive -- it overwrites it all raw.)
By that do you mean it doesn't care what files are on the drive or what format it is, or both?

Quote:
You could even keep the backup "fresh" in a similar way to the online backup, once you have it, since almost nothing but user files are going to change.
So what you're saying is, I would make a mirror of the entire system hard drive, and then weekly, could do backups, more similar to the online style, where I just upload file changes?

This would be opposed to downloading a tarball onto the drive, and then moving forward downloading new tarfiles on a weekly basis?

Choosing between these options should all be kept in the context that, at some point, I am going to ideally be installing the RAID 1 backup to do nightly backups. At that point, the external drive will be either kept in a separate location in the office or as you have suggested kept off-site (if possible) and brought in to do weekly backups.

When I do install the RAID system, is it better to have them simply backup data files or for them to act as a mirrored system? Planning ahead could help determine what should be done now.

Finally, if I really wanted to, could I do both? Would there be any advantage? disadvantage?

Thanks!
