#876 Re: General matters » Many Snapshots for one backup » 2020-04-09 11:57:59

[b]©XSIBackup-DC[/b] (as well as all other versions of ©XSIBackup) request an snapshot to be taken to the [b]©ESXi[/b] system. They don't create the snapshots, they just wait for the snapshot to complete before proceeding with the backup. As the information returned by ©ESXi is that the snapshot did not complete ©XSIBackup-DC believes that and returns an error.

Even in the event that you receive an error, some backup might still be taking place, we can't conclude that from the information you provide, as it will in turn depend on so many facts. The simplest way to find out is to look into your backups, check them via the --check argument and eventually restore some of them. Please be aware that you might need to arrange the .vmx file to point to some previous snapshot or .vmdk file, as when some error like that is raised the backup process might not be able to re-arrange the disk paths automatically. In any case a working -flat.vmdk is all you need to restore a VM.

Now the matter is [b]why is your VM resisting or failing to be snapshotted?[/b]. You will need to get into the guest OS and check the logs or event viewer to retrieve information about the error that was raised at the moment to take the snapshot. This is usually caused by some service not being quiesced properly (in case you chose to quiesce the guest OS, which you did not state so far).

[b]What is quiescing?[/b]
Well it's a process by which the OS asks some service, usually a busy one, to write whatever it has pending in its I/O queue and halt for some time (usually less than a couple of seconds) while the snapshot file is being dettached and prepared to be written to. This ensures that all data written to disk by the service, usually a DB one, is consistent in the backup.

[b]Why would some quiesced snapshot fail?[/b]
[b]©VMWare Tools[/b] needs to be installed as well as some additional components that your database server might need in order to be in coordination with the snapshot process. You may not have VMWare Tools installed, they might be outdated, you may be lacking some additional components your guest needs to perform this operation correctly. Windows servers are usually harder to configure than Linux ones, the latter will usually work like a charm just as long as you have [b]©VMWare Tools[/b] installed.

[b]What if I have some ancient DB server that can't be quiesced by ©VMWare Tools?[/b]
Just perform a [b]warm[/b] backup. That will turn the VM off, create a snapshot that will be consistent (as the VM is off), then it will turn the VM on on top of the snapshot and perform the backup. In the worst of the cases your server will be down for one or two minutes.

We don't know what version your ESXi system is, we don't know what version of XSIBackup-DC you are using, we basically know nothing.
Please provide all the details. If you still suffer from the same issue, contact support to debug your scenario.

#878 Re: General matters » error using --rotate » 2020-04-04 18:06:17

You haven't still provided your backup job. There's very little we can do without knowing all the details, but guessing.

You get the same simple straight message: [b]sort: out of memory[/b]
By now [b](c)XSIBackup-DC[/b] depends on [b]sort[/b], in any case you could still be running out of memory if it didn't, so:

- Increase your system's memory.
- Run the backup as a remote IP backup to the CentOS 8.0 box so that the load is shared amoung the two CPUs and memory.
- Use a bigger block size to help the problem, i.e.: 10MB block size will require ten times less memory to prune the same amount of data.
- Don't prune, rotate backups to two or more repositories.

#879 Re: General matters » Explanation of parameter --exec is missing in man page » 2020-03-30 10:00:17

You haven't even provided the job, so we are discussing about somehting we haven't even previously set. If you run remote commands with --host, that argument can still be helpful, not may people do, so we try to offer general advice here.

#880 Re: General matters » XSIBackup DC Manual Errors? » 2020-03-30 09:56:57

If you cut & paste text from the manual you will most probably be suffering from character substitution. Maybe some white space character you pasted to your shell is not what you think it is. Write the argument manually.

#881 Re: General matters » Question to XSIBackup-DC_Manual » 2020-03-30 09:55:09

The path of the binary, binary files also have paths.

#882 Re: General matters » Backup still working? » 2020-03-30 09:53:58

It should be much, much faster. That slowness can only mean something is quite not working or clogged at the time to perform the backup job.

#883 Re: General matters » error using --rotate » 2020-03-30 09:51:03

You have some little dependencies in the server OS like sort binary. In your case it looks like it's running out of memory

sort: out of memory

:
- What OS are you using as the target server?
- What version is it?
- What is the size of the repository you are trying to prune?

#884 Re: General matters » Explanation of parameter --exec is missing in man page » 2020-03-24 14:05:37

The GUI might add it where needed, it's a deprecated argument to users, but don't delete it if the GUI puts it there.

#885 Re: General matters » Watch ongoing backup jobs stuck » 2020-03-24 14:03:44

We are sorry but we aren't really getting what you mean.
Please post the output where you find something not working as you expect and explain the reason that led you to think so.

#886 Re: General matters » error: cannot copy VMX file, details: Warning: Output redirection not » 2020-03-20 16:03:04

As you stated in a previous post you are Rsync'in to a Unix system, 8c)XSIBackup is not compatible with Unix as a server. That doesn't mean that you can't get it going with Unix, just that we don't support it.

#887 Re: Rsync » temp-dir on a different file system than the destination file » 2020-03-20 16:00:57

(c)XSIBackup is not compatible with Unix. You may get it working, we don't support it tough.

#890 Re: General matters » Cleaning tmp folder » 2020-03-17 18:10:17

[b](c)XSIBackup-DC[/b] does delete those folders after each backup or replica cycle. Please make sure that the user you use to run [b](c)XSIBackup-DC[/b] does have rights to delete them. They are typically kept at /tmp which should have open permissions for everyone

#891 Re: General matters » Multiple Jobs » 2020-03-12 20:36:23

Great, you answered yourself. Regards.

#892 Re: General matters » Xsibackup Free doquiesce » 2020-03-12 20:33:40

Quiescing has nothing to do with including the memory in the backup snapshot which is BTW perfectly useless. It is a kind of almost useless option, as the backup snapshot is deleted right after the backup completes loosing all the data in it, thus including the memory in the backup snapshot will only contribute to make the snapshot creation phase take much longer.

Invalid arguments are ignored.

#893 Re: General matters » Doing a OneDiff backup - Can I still create a manual snapshot? » 2020-03-08 12:46:27

[quote=AndersG]Also, with XSitools it now creates a full backup in a new folder, named "20200306200006" for every new backup.[/quote]

XSITools is a block deduplication engine:

#894 Re: General matters » Doing a OneDiff backup - Can I still create a manual snapshot? » 2020-03-08 12:45:15

[quote=AndersG]OK. When I do so, it does not remove the "xsibackupdiff 1" snapshot. Is that to be expected? Should I leave it there or remove all snapshots before I turn back to OneDiff after the upgrade?[/quote]

It does not remove ANY snapshot. If you have some previous "xsibackupdiff" snapshots that you don't want, remove them.

#895 Re: General matters » Email problem with jobs » 2020-03-08 12:43:03

We can't verify each individual mail server. If you can't get it to work just switch to some gmail.com, yahoo.com account.

#896 Re: General matters » xsibackup is trying to backup every folder in the same dir as *.vmdk » 2020-03-05 16:40:55

Rename the spare disk and place it in its own folder named after the VM

#898 Re: General matters » Upgrading from Free to Pro? » 2020-03-04 10:37:10

Don't forget to backup the whole directory, it's just some KB and you may miss some files afterwards, such as the [b]conf/smtpsrvs[/b] file or the RSA keys.

#899 Re: General matters » Doing a OneDiff backup - Can I still create a manual snapshot? » 2020-03-04 10:34:35

Onediff will force the VM to have just its own snapshot, thus trying to keep a custom snapshot will fail, as it will be deleted on the first Onediff cycle (the first full copy). To keep that snapshot and still backup your VM you could use [b]--backup-prog=Xsitools[/b] or [b]--backup-prog=Xsitools[/b], but that would perform a full copy everytime.

You can also use [url=https://33hops.com/xsibackup-vmware-esxi-backup.html](c)XSIBackup-DC[/url] which will always preserve any pre-existing snapshot with any kind of operation, you may contact us to size whether that change would benefit your current backup set up.

#900 Re: General matters » Upgrading from Free to Pro? » 2020-03-04 10:25:22

You should backup and remove your current installation of the Free version, as the default installation dir has changed from [b]/vmfs/volumes/datastore1/xsi-dir[/b] to [b]/scratch/XSI/XSIBackup-Free[/b].

[url]https://33hops.com/xsibackup-uninstall-procedure.html[/url]

Then install the Pro version using the online script.

You can then easily overwrite the [b]conf/smtpsrvs[/b] file and the [b]_rsa_[/b] key files in the root installation dir by your existing ones in the Free version installation dir. You can use your pre-existing jobs too,  you will have to edit them to reflect the new installation dir though.

Edit the first and last lines and change [b]/vmfs/volumes/datastore1/xsi-dir[/b] by [b]/scratch/XSI/XSIBackup-Free[/b] to point to the new installation dir.

Contact support if you need some especific help, nonetheless the procedure is quite straight as outlined above.
