first thing first. get your drives down to ~%80 usage! degragging the
drives is useless unless you make some room.

very good at long term performance and reliability. i have worked with

Try using `iostat 3` or similar during a backup. Typical 7200 rpm IDE
disks can't do more than 100-150 IOP/s or so.

Yes, i have backups who take much longer. Just reading in the german

The problem is likely your disk configuration on your backup host.

Running top and vmstat 3 while a backup is running works very well and
will help track down where the bottleneck is.

allocated to cache and buffers, also displayed with top.
BackupPC_dump is rather I/O intensive. It is very common for all free
memory to be allo

Hello Hendrik,
did you ever run a hdd benchmark on your backup host? < 1 MB/s for the

Hello Hendrik,
it isn't readable (at least very good ;) ) and what kind of trasfer
