Hi there,

I recently signed up for S3 and I want to use S3sync to backup my Zimbra backups folder. this folder contains a weekly full and 6 incremental backups, the full is about 800MB and the incrementals are about 20-80 each.

they rotate and each week they get deleted on a rotation.

anyhow I setup my script to use s3sync with ssh (even though the files are encrypted using GPG I still would like to use ssh)

I get the connrection reset by peer loop that was supposed to be fixed.

the command I used: s3sync.rb --progress -rs /backup publickeyhere-zimbra:

Create node 21_ZimbraBackup_20100526_FULL.1.dar
Progress: 197341184b  260218b/s  24%       Connection reset: Connection reset by peer
99 retries left, sleeping for 30 seconds
Progress: 118877184b  82078b/s  14%       Connection reset: Connection reset by peer
98 retries left, sleeping for 30 seconds
Progress: 471596032b  162847b/s  57%       Connection reset: Connection reset by peer
97 retries left, sleeping for 30 seconds

notice the performance is also pretty slow. Now of course this can be my server but it is in a real datacenter (not my basement) and with other backup servers I get 2 to 8MB/s.

thanks for any advice/help!

I don't know what I could do to help with this.  The http transfer stuff is all down in the ruby library.
