While I too use SIGINFO, I doubt the extra pv pipe will slow anything
down given that disk read/write is by FAR the rate limiting step...

For those not familiar with dd, it doesn't display progress when working.
And dd'ing a 2 TB drive can take a long time. If you want progress, use this:
dd dd if=/dev/sdb1 bs=1M | pv | dd of=/dev/sdc1 bs=1M

The fastest way to do this is to do a blockwise copy of the old
drive/partition to the new, then expand the filesystem with resize2fs or

Hello,
I am trying to move data from a 2TB hard drive to a 3TB drive and am having
space issues. I am using:
rsync -aHAXv --delete --progress /mnt/olddrive/ /mnt/newdrive/
To copy the data from the old to the new. I noticed that this process
tanked so I ended up running it for individual fol

which leads to a 1:x-1 performance hit because of that parity compute, wait,

I'm not sure if speed is an issue here since all backups are taken
over night.

Hi,
Were're about to change one of our backup server from raid1 to raid5.
What would be the safest way to backup BackupPC and restore it to the
new system?
Thanks for all suggestions.
