Hi Les,

Is there a way to force protocol version 30 instead? Obviously with v28 the "--no-incremental-recursive" does not have any effect. > I'm not actually sure from your error message which end was out of > memory. How do things look on the target system while the backuppc > backup runs? The host to be backed up seems to run out of memory. Has 4GB and while rsync runs the number of "page cache" increases so just around 100M remain as free memory. Though, rsync does not use more than 112M. Swapping apears but I was not able to catch the exact moment when the oom appears. > Memory use should relate to the number of files more than the total > size.

See the output of "find DIR -type f | wc -l" for various dirs: bin: 86 dev: 43 lib: 2999 lib64: 281 media/: 0 opt/: 0 root/: 21 selinux/: 0 store/: 0 tmp/: 1 boot/: 22 etc/: 1222 mnt/: 37 proc/: 37101 sbin/: 190 srv/: 44 sys/: 6831 usr/: 54306 var: 7176 The huge directory is not to be backed up at this stage because it is mounted and rsync got the "-x" option. But for completenes: home: 57949 Any further ideas?
