similar to: rsync vs. iOra

hello, I'm new to this list. here is my question: I would like to synchronize two computers (say the home one and the job one) using zip drives or similar (cdroms, etc), since modem lines are quite slow and expensive (in Italy). I though I could produce the "signature" of files on home computer, store it on a zip, go to job, run rsync to copy the missing or altered files on

Hi, I am thinking about a non-standard usage of rsync (at least not mentioned in the man file) I want to synchronized my collegues home directories(trees) each night AND store rsync's internal updating commands (reversed) to be able to restore the state of a directory the day before. This would require - saving the internal updating commands in a separate directory - reversing these commands

Hi, can someone tell me whether applications can expect the write requests they make to be executed in order? For instance, suppose an application requests that a file be deleted, and then that another file be moved to an unrelated place. Will these events always happen in that order? Or to put it another way, if something unexpected happens in the meantime (say the computer crashes), is it

A while back, I asked if there had been any consideration in making rsync support direct ssl (as opposed to just ssh). I've been looking around for a secure way (e.g. encrypted, so passwords are never in the clear, and even content is obscured from sniffers) to allow a set of limited-trust users (limited-trust being defined as mostly customers, whom you trust with their own data, but not with

Can someone explain to me what is happening here: ~ $ touch foo ~ $ ln foo bar ~ $ ls foo bar bar foo ~ $ mv foo bar ~ $ ls foo bar bar foo I try to move a file over a hard linked copy of itself and the move fails, but there is no error. Is this the intended behavior? -- Ben Escoto

If I want to make sure a file has really been deleted do I have to: 1. fsync the file 2. fsync the directory the file is in 3. both? Much thanks. -- Ben Escoto

Hi, I vaguely remember some talk on this list of a virtual file system of some sort for rsync. The goal was to handle cases where the file system on the original side carried information (permissions, ownership, special file types?) which couldn't be recorded directly on the receiving side. I think the proposal was to record as much of this information as possible in the receiving

>From what I understand, the incremental rsync algorithm saves on network bandwidth, but does rsync then just merge that delta data to end up with the new version and full sized file on the destination filesystem? I have these Microsoft Entourage databases files that modified often and can be a few gigs in size... I want to back them up with rsync, but if the whole file is backed-up each

I understand why the following happens ($.proto delegates to get, which ascends the parent hierarchy up to globalenv()), but I still find it anti-intuitive: > z <- 1 > y <- proto(a=2) > y$z [1] 1 Although this is well-documented behavior; wouldn't it uphold the principle of least surprise to inherit instead from baseenv() or emptyenv()? (See attached patch.) Spurious

Hi, after some searching i didn't came up with an answer so please excuse if this is a total newbie question. My problem: I have server A which has a big (>500G) database like file. On server B i want to have a copy of this file which i don't want to copy each time but sync the deltas so that only the deltas are written once a day. Bandwidth between A and B isn't the problem.

I'm trying to use the rsync algorithm for incremental backups. After a quick look at rsync I saw the batch mode operations, and I thought that maybe I can modify them for incremental backups. What is needed is to add an option to save the checksums of all the files of the level 0 backup and a second option to use the level n checksum to calculate the delta batch files for the level n+1

I'm still pretty new to running a mail server, but one thing I've come to appreciate over the years is a good backup strategy. Since I have always run my own servers for practice and for personal use I don't have access to Enterprise backup solutions. Because of that I usually just fall back to scripts and tarballs and offload the content on a regular basis. Right now I'm

Hello, I am a french student and I have written a technical report on an extension of the rsync algorithm to crypted files. I started from the situation of a client machine A user who doesn't wish to save an original file v0 and its successive versions v1 v2 v3 ... on a distant server B but rather to save the private ciphering of these files on the server. Let C be the cipher algorithm and

I'm interested in these very questions (librsync-rsync relationship, remaining limitations of rsync, active prospects for ground-up rewrites), Google searches for rsync info have proved a little too vague due to the programs ubiquity. Much has certainly changed since this was written, could some people with knowledge in these areas could update martin's response for the state of rsync,

I was wondering if the following is possible, or is planned for rsync. I backup a number of databases with rsync that work very well with the rsync algorithm. Ie, I am backing up a gigabyte+ database over a dial-up speed link and it doesn't take very long, so the daily differences in the files are obviously very small compared to it's total size. I am storing many copies of this database

Hi There, I've been toying around with the code of rsync on and off for a while, and I had a thought that I would like some comments on. Its to do with very large files and disk space. One of the common uses of rsync is to use it as a backup program. A client connects to the rsync server, and sends over any changed files. If the client has very large files that have changed marginally,

Hi All, I am posting this querry second time. What i need is-- {Is there any command by which I can get only the updation of file ie only the incremental?. Suppose I have a text file say ss.txt of 3KB in size and I have taken the backup of this file. Now I am making the changes in to this file(ss.txt) by adding 1KB of data. Now I want this 1KB data (in to a new file) when I take the

I have 2 drives in a Linux 7.1 server , 1 primary and 1 secondary. I am trying to clone to the secondary slave drive and be take the primary out and change the slave to primary and boot from it. The problem I am having is that it the copied drive will not boot, It is not getting the lilo boot and config properly. When I try to boot the copied drive , it boots to a Blank screen with an

Is there any chance for rdiff ? I need to frequently synchronize big text file (60MB+) undertaking small changes and I am interested in differences between the subsequent versions [DNS RBL data in dnsbl format, 1E6+ lines of text, new version every 20m, on average 50 new entries (lines) in every synchronization] I would like to get (small) diff file as result of rsync session and apply it to
