I am new at backuppc. I am backing up 250GB from one machine to another
with backuppc. Both machines use debian lenny as the os. 2.4ghz
machines with 4GB ram in client and 2GB in backuppc machine. Both
drives are sata.
Initially I used rsync and it took 7 hours for a full backup and 5 hours
for an incremental. I did every tweak I could find on to improve speed.
I switched to tar and it still took 7 hours for a full backup but it
only took 10minutes for an incremental. I modified a few files to make
sure that it was working. The modified files were indeed backed up.
Why is my rsync so much slower to do an incremental backup than tar?
Have I made an error?
It is hard to believe that tar can be so fast with the incremental
backup with that much data?
Are there any serious problems with using tar?
Any advice appreciated! Thanks!
