[BackupPC-users] ALRM/PIPE backup errors

[Kris S. A. <kr...@os...>]

Having some issues with a particular host.  Backing up using rsync over 
ssh, with the server being backed up over the Internet (~50ms round trip).

First error (predictable failure when it hits a group of ISO's):

create   440     33/33   691036160 
foo.com/ssl/clients/foo/debianslim_0.3-1.iso
   create   440     33/33          55 
foo.com/ssl/clients/foo/debianslim_0.3-1.iso.md5
finish: removing in-process file 
foo.com/ssl/clients/foo/debianslim_0.3-2.iso
Child is aborting
Done: 25596 files, 877706669 bytes
Got fatal error during xfer (aborted by signal=ALRM)
Backup aborted by user signal


So I put the ssl directory in the exclude list, but now this:

pool     640   1008/33     7458690 jessipo/web/mp3/night at the opera/07 
- Subhuman.mp3
Read EOF: Connection reset by peer
Tried again: got 0 bytes
Can't write 16 bytes to socket
finish: removing in-process file jessipo/web/mp3/night at the opera/08 - 
Stroke Of Luck.mp3
Child is aborting
Done: 40357 files, 1575362485 bytes
Got fatal error during xfer (aborted by signal=PIPE)
Backup aborted by user signal



What is giving it the ALRM and PIPE signals a is this the root cause of 
the abort?  Filesystem is reiserfs.  I don't see what is special about 
this particular mp3 or ISO (except maybe filesize with regards to the ISO).

The connection reset by peer might be an issue.  Reset ssh tunnel due to 
Internet jitter?  Are there any timers I can adjust to deal with backing 
up a system over the Internet?  I already tweaked the ping times to 
allow 200ms as acceptable.
