I am using rsync to backup mail on a mail-server with 3000+ mail accounts [only 1550+ are in use]. Using this command:
/usr/bin/rsync -a --delete /var/imap/mailarray /var/oldarray This mail server only receives about 2GB of mail per day. Rsync is run without shutting down any services. About half the time I run rsync the system slows down to the point that mon starts sending me pages. To fix it, I have to log in, and kill the rsync process. Is there a more efficient way to run rsync without down time ? Or should I be using something else for backups ? After the last failure I ran rsync in dry-run mode and I got this error: imap:~# /usr/bin/rsync -axn --delete /var/imap/mailarray /var/oldarray -T /tmp --timeout=10 building file list ... rsync: writefd_unbuffered failed to write 4092 bytes: phase "send_file_entry": Broken pipe rsync error: error in rsync protocol data stream (code 12) at io.c(515) imap:~$ rsync --version rsync version 2.5.6 protocol version 26 file-system ext3: raid-card:0 #system file-system and mail backup /dev/sda5 on /var/oldarray type ext3 (rw,noexec,nosuid,nodev) [] raid-card:1 #mail storage /dev/sdc5 on /var/imap type ext3 (rw,noexec,nosuid,nodev,usrquota) [] -- ------------------------------------------ Ted Knab Chester, MD 21619 ------------------------------------------ 940216d6021602a41607166696c656c202778696368602d65616e637 02940226c696e646c69702c6f667560256675627478696e67602a416 0716e6563756e2a0
