Hello, I have a system that currently uses rsync (via rsnapshot) with --link-dest enabled to backup our mail store... If I change the permissions on the source maildirs, will this cause everything to be transferred again? Meaning, will rsync see everything as 'modified', thus creating a new copy of the entire mail store on the backup target? Or will the newest backup directory just

You could try using an automounter, like autofs, in combination with sshfs. It'll be slower, possibly a lot slower, but it should be more reliable over an unreliable connection. I've been using: remote -fstype=fuse,allow_other,nodev,noatime,reconnect,ServerAliveInterval=15,ServerAliveCountMax=40,uid=0,gid=0,ro,nodev,noatime :sshfs\#root at remote.host.com\:/ BTW, I'm not sure

Howdy all, I'm using rsync in conjunction with backuppc and have been backing up this share without incident for almost 3 years and it has decided to go and hang on me. Other shares on the same machine sync fine with identical settings, and nothing has changed on the backup end other than some routine dist-upgrades to keep update on security patches. I checked the apt cache and no rsync

Is this possibly a problem with dovecot 0.99.10.9? Maybe it's been fixed in a later release? Might it be a security issue?

Is it possible to mix maildir and mbox formats with dovecot? For example, I would like ~/mail to be in maildir format yet keep the inbox (/var/mail/%u) in mbox format. If so, how may I go about this? Or am I stuck not being able to create subdirectories in ~/mail? Cheers, Shane

Does anyone have advice or pointers on good documentation on how to convert a system from using the Mbox format to using Maildir? I recently upgraded to Fedora Core 2 from Fedora Core 1 and discovered that UW-IMAP was gone. So I switched over to using Dovecot. So far so good. But I would like to convert my system to start using the Maildir format. How easy is this to accomplish? Can I keep

It'd be pretty cool if rsync supported use of O_DIRECT on platforms that support it, with or without my odirect package: http://dcs.nac.uci.edu/~strombrg/odirect/ I say this because rsync is sometimes used to move a mountain of data, just once. So there's little point in rsync toasting one's buffer cache. I gather there's something like O_DIRECT on windows too, but it's

Hi, there is an issue left in 0.99.10.5 which (I think) is a problem with imap status flags. It shows up in two places: (1) When new mail is delivered to the inbox, the last read mail changes to "unread". (2) When you move mails from the inbox to another folder with Mozilla (1.6 on win32, Linux, NetBSD), they are not removed from the inbox, effectively performing a copy instead of a

I've tried to write the new mbox code in a way that it could be moved into generic flat-file library with mbox-specific code being implemented on top of that. The code would be useful for all formats that require modifying message headers to store the metadata. How many such are there? I suppose all such formats could be implemented by separating mails into 3 logical parts: - header

I'd like to use rsync on a production box that has a great deal of memory-cached filesystem in use at all times. Is there any way, or any other tool, that will do a "slow" copy? purposefully not busting the cache by copying things as fast as possible? "nice" does not work, of course, as that is a cpu scheduling control. What I want is basically lowest-priority or

I configured dovecot on a Fedora Core 2 system - the version that comes with FC2. I was using it with a RHEL 3 NFS server. Dovecot would again and again get stuck trying to grab an fcntl lock, even though I specified that it should only use dotlocks in dovecot.conf. Sometimes it would segfault (leaving things locked?). Often there would be two dovecot imapd processes for the same user.

Is there any way of increasing rsync's block transfer size for when you need to transfer data from one filesystem to another on the same disk? Using a large blocksize tends to decrease track to track seeks. If I put a large dd or something in between two tar's in such a situation, I see over double the throughput on an AIX system (1M vs 64K). Thanks. -- Dan Stromberg DCS/NACS/UCI

Hello rsync people Today I was recovering data from a beginning-to-fail external USB hard disk. I started with my usual 'rsync -av --ignore-errors <source> <dest>', and that was fine until it got to the first I/O errors. It paused but continued after the first couple of errors, but then the disk started buzzing and rsync gave error messages for every file (I'm afraid

Well, here's one thing that could make them, even if they're being created only directly, not over NFS. I'm watching the directory you're syncing into. I open the file while it's still there. You delete it, and

Included below is a shar archive containing two patches that together: 1) make backup files get their setuid and setgid bits stripped by default 2) add a "-s" option that allows backup files to continue to have these privileges This means that if you update a collection of binaries with rsync, and one or more of them has a local-root security problem, the backup file(s) created when

If reducing the MTU is helping, you might look into turning on Path MTU Discovery. NFS can be fast for large transfers if you tune it. http://stromberg.dnsalias.org/~strombrg/nfs-test.html NFS is not terribly secure though - at least v2 and v3 weren't. Not sure about v4.

Hmmm, looks indeed like changing the mtu helps, strange thing is that with the bigger mtu sometimes I had no problems and often TB are copied without problems. Problem is I can't test the connection that much because the connection has been established by a third party and it is just some vlan without any hops. But thanks for the link to the nfs-test that looks interesting!

As far as I can tell rsync doesn't support this. How hard would it be to implement this? Is it trivial enough to just change the calls in the code with sed? I think this can significantly reduce CPU usage and increase I/O speed when dealing with fast storage solutions. It can make a huge difference when say transferring 30TB of data. Here are some tests I did. So far the only thing I know
