similar to: skipping and not finding batched updates with extra --link-dest?

I already asked this question before, some time ago (a few months), but got no reply. We're using a backup system based on rsync and batched updates. Quite often I see a situation when rsync refuses to apply next batch with the following messages: applying f0002.rgs-podm.ru 142 (Skipping batched update for "etc/cron.d/sysstat") (Skipping batched update for

I'd like to know if it's possible to run rsync in batch mode, but avoiding transferring the deltas, just generating the batch file. I'm looking for such a behaviour because overnight backup sessions are often interrupted and daily snapshots (--link-dest) of remote servers are truncated. Specially the ones using slow links. Options: 1) Using -write-batch when mirroring volume

I don't believe there is anything you can do with the batch options for this. If you added a --write-batch to each of those you would get 3 batch files that wouldn't be read without a --read-batch. If you also did a --read-batch that would contain differences between a backup and the backup before it so rsync would still have to read the backup before it to understand the batch (and this

If you are using ZFS then forget --link-dest. Just rsync to the same zfs mount every time and do a zfs snapshot after the rsync finishes. Then delete old backups with a zfs destroy.

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Yes, but there are issues to keep in mind... Normally --link-dest is used to keep previous copies (to make a backup system) and the target directory is always empty. In this mode - --inplace and --append-verify would be irrelevant since rsync will always be either making a link or writing an entire new file. However, if you have an unstable link

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I mean instead of having --link-dest=previous_backup and the target being empty (or starting that way in your case) you cp -al the prevous_backup to the new "incomplete" one. Now you have a tree full of all hard links. Now you can rsync to the target without any - --link-dest reference. You are right about the other options except that

Hello. I need that during today's backup, the metadata about the files is saved in a file, so that tomorrow when creating a backup with the option "link-dest" instead of this option I would specify a file with metadata, then rsync will not scan the folder specified in "link-dest", but simply reads information about this folder from a file with

In virtualized environment there are mainly three problems related to spinlocks that affects performance. 1. LHP (lock holder preemption) 2. Lock Waiter Preemption (LWP) 3. Starvation/fairness Though Ticketlocks solve fairness problem it worsens LWP, LHP problems. Though pv-ticketlocks tried to address these problems we can further improve at the cost of relaxed fairness. The following patch

Hi! I use rsync batch mode for incremental backups. That is, I create an on-line backup with rsync, and use the --write-batch flag to additionally generate my delta, which I send off-site. To restore, I download a full backup and apply the deltas with --read-batch. This is quite a lovely setup, in principle. However, restore has give me problems. Before I detail them, let me ask: Are a lot
