Hi,

I've a problem with the initial backup of a vista client, called "myclient".
This client ist connected over internet with an 1Mbit/s upload bandwidth and 
have
100GB of storage to backup.
Unfortunately the internet connection will be interupted each night for 5 
minutes.

2009-03-31 23:59:19 Backup failed on myclient (lost network connection during 
backup)
2009-04-01 00:00:00 Next wakeup is 2009-04-01 00:15:00

Now, 20:41, I found 5200 files with 5GB in /var/lib/backuppc/myclient/new and
27158 files with 522MB in /var/lib/backuppc/myclient/1, the last partial backup.

If the connection interrupts at 23:55 short time later the /new is empty and the
/0 contains the same count of files and MBs as before.

Whats happening theire?
How to continue an interrupted backup?

My rsync parameters are:
--server --sender --numeric-ids --perms --owner --group -D
--links --hard-links --times --block-size=2048 --recursive --one-file-system 
-vvv

Should I use --ignore-times too?

I did not really understand the logic of rsync ;-)
In the clients logfile I found out that the file "file1" will be saved after
16 hours in the first run and after 12h, 8h, 6h again in the following runs.

2009-03-30 07:45:19 full backup started for directory C
:       16h
2009/03/30 23:54:01 [2564] send_files(1748, file1.JPG)

2009/03/30 23:54:43 [2564] sending file_sum

and the next time it was send after
2009-03-31 00:05:17 full backup started for directory C

2009/03/31 12:39:04 [804] send_files(1748, file1.JPG)
