The only reason I can imagine why storebackup may stall (and stalled in the past) is because of network problems (esp. via NFS).

Storebackups starts several programs (fork/exec) in parallel and waits for them to finish (at some point). This could be a "typical" situation where it may "stall" if these processes are stalling.

Can you run your backup (additionally) to a local (usb) drive to check if the problem is originated in the network?

btw, there should be no need to use the saveRam option if 1.5 GB are available - or do you save several millions of files?

Normal servers via SSHFS

Both OS's are CentOS 5.

About 1.5G of memory free when storeBackup is running (using the saveRam option).

Load is below 0.75 on both servers at peak. Dual quad cores on both.

On what kind of machine do you make the backup (NAS, normal server, OS, memory, ...)?
Do you make your backup over a network? NFS?

StoreBackup appears to constantly stall every few days.

The last line output was:

PROGRESS  2010.05.13 18:12:01 14197 67024 files processed (1.8G, 756M) (1972497738, 792820661)

It's now well after 21:00:00.

Configuration options are below. I've tried both with and without latency option. Love the solution, just wish it'd work!

/usr/local/bin/storeBackup.pl --saveRAM .....

# .configs/global.conf
writeExcludeLog = no
verbose = no
progressReport = 2
printDepth = yes
keepRelative = 1d 3d 7d 31d 100d
exceptRule = '$size > &::SIZE("50M")' or '$file =~ m#error_log$#'  or '$file =~ m#virtfs$#'  or '$file =~ m#tmp$#'  or '$file =~ m#trash$#'  or '$file =~ m#.ssh$#' or '$file =~ m#\.bash.*$#'
ignorePerms = yes
lateLinks = yes
lateCompress = yes
doNotDelete = yes
cpIsGnu = yes
linkSymlinks = yes
highLatency = yes
