  1. Hi Community, since we fixed the VSS errors Event ID 8194 [1] a couple of weeks ago, we are getting in Retrospect log the error message (basically translated): Backup of Writer "NPS VSS Writer" failed, Error -1101 (File/Directory not found) Backup of Component "NPS Database" failed, Error -1101 (File/Directory not found) This behavior occured on a Windows 2008 R2 (domain member) server very short after we fixed that VSS 8194 error and since last week another 2008 R2 server (domain controller) is affected. The event log of the server doesn't show any problems related to the backup task or particular to the NPS error message. Also a backup with the windows onboard tool wbadmin doesn't show this NPS errors. BTW: NPS isn't used in our environment and is neither on the member server nor on the domain controller configured. I noticed this feature first time after I saw it in the Retropect error message. [1] http://www.retrospect.com/en/support/kb/event-id-8194-vss-error Thx & Bye Tom
  2. Hi Community, we changed our single server Exchange setup into a DAG with two servers in an active/passive setup. I read the Exchange agent manual but the only thing I figured out is that we need just a license for each Exchange server to backup, but no further information about backup a DAG was available. So I've a few questions: 1) Is it possible to backup only the passive node in a DAG envirionment? 2) How does Retrospect deal with the transaction logs? 3) Are there some No-goes which are not present in a regular one server setup. Currently we are using Retrospect 10.0.2.119 and Exchange 2010 Standard RU15 Thx & Bye Tom
  3. Hi Community, I have to reinstall Retrospect for some reason, is it possible to keep the backup sets and catalog files? And how do I setup Retrospect to use the former catalog files and backup sets? Thx in advance & Bye Tom
  4. Hi Lennart, got it, thanks. For my particular problem the Retrospect support recommends to trash the config file but I prefer a regular fresh installation for that. The manual describes the procedure at least with keeping the catalog files and backups sets, very good this is the minimum requirement but it would be really great to keep the scripts also, otherwise I have to print each script to keep in line with the former schedule. There is no way to extract the scripts, I guess? BTW: I can use the license keys which are displayed in the license manager again or do I have to request new keys? Thx & Bye Tom
  5. Hi Community, today I did a deeper look into the result of a transfer from a disk backup set to a tape backup set instead only a plausibility check. I found out that the count of files and amount of data differs. I transfer three disk backup sets, one for each server partition, to one tape backup set. In one of these backup sets are more than 10.000 files with 150 GB data missing in the tape backup set, if I compare the log file of the transfer and the properties of the source backup set: http://wiki.prontosystems.de/animation/retrospect/Retrospect_01.png But if I create the sum of files both the target backup set and the source backup set I get the same result http://wiki.prontosystems.de/animation/retrospect/Retrospect_02.png And if I compare the properties of the target and the source backup set I get the same count of files but around 150 GB are missing: http://wiki.prontosystems.de/animation/retrospect/Retrospect_03.png http://wiki.prontosystems.de/animation/retrospect/Retrospect_04.png Does anyone know where the missing data is or why I get different results? Note: There is no deduplication enabled: http://wiki.prontosystems.de/animation/retrospect/Retrospect_05.png Note: The volume where the data is missing is an AFP Share on a Windows based file server (ExtremeZ-IP). Like Apple style there are many extended attributes / alternate data streams in the volume. I don't know if Retrospect has different ways to determine the file count but 150 GB extended attributes is quite impossible, so there is something wrong, I think. Thx in advance & Bye Tom
  6. Servus Lennart, puh I try to avoid this because the affected volume is the largest volume we have with about 1,5 TB data. But I counted the files listed in the single backup runs, started with the full backup on sunday and each incremental and at least the file count is equal in both backup sets. I think I will open a support ticket on monday. I report the results asap, if there are any... Thx & Bye Tom
  7. Hi Community, today we made the experience to work with a desaster recovery on an Exchange server 2010 SP3. We have a broken hardware and reinstalled the Exchange server on a virtual machine with the RecoveryServer switch from the Exchange setup and restored the databases from a Retrospect Exchange backup into the new server. The databases and transaction logs are located on a E:\ partition. The restore works as long as we restored databases which are smaller than the free space on the C:\ partition is. It seems that Retrospect does first a restore on the C:\ partition and after this is complete it copies the database to it's originial destination. If the free space on the C:\ partition is smaller than the largest database, the C:\ partition is running out of free space and the restore terminates with an error "Disk full". So it is a normal behavior that the databases are not located on the C:\ Partition. It is best practice recommended from Microsoft to move the datadases on another partition. So how can we avoid this problem that Retrospect ist doing a temp restore first on the C:\ partition? This is a critical question... Thx & Bye Tom
  8. Servus Robin, I found the checkbox, thx a lot
  9. Hi Community, because of some problems with Retrospect I wish to upgrade from version 9 to version 10 with a fresh install. Is it possible to keep the scripts, catalouge files and backup sets? Or is an inplace upgrade as good as a fresh installation when changing a major release? Thx & Bye Tom
  10. Fresh Install

    Servus Lennart, the installation of the minor release update to version 9.5 didn't solve my problem so that was the reason why I thought a fresh install would be the next step in my troubleshooting. But first I can give an inplace upgrade a chance, I've nothing to loose... Thx & Bye Tom
  11. Hi Community, since a couple of weeks we have problems with the communication between Retrospect server (9.5.3.103) and our Tandberg T40 Library [1]. For example if I drag a tape out of the drive back to it's place in the library using the Retrospect devices interface, a task is shortly listed in Retrospects task monitor, just for a part of a second but nothing happens, finaly the task is listed as succesfull done in Retrospects task history but the tape is still in the drive. Or another problem occurs sporadically during the transfer of a disk backup set to a tape backup set, than the media change from the first tape to the second of this backup set doesn't take place but the job keeps alive and blocks the following tasks. If I move the tape with the control interface of the library itself, everything works promptly without any error. We already changed the SAS HBA in the Retrospect server but the problems are still present. Does anyone have a clue how I can fix that problem? [1] http://www.retrospect.com/de/devices/a0JU00000027EATMA2 Thx & Bye Tom
  12. Servus Johnny, Okay since we had to buy a service contract with the last version it should be no problem to get the new version 10.x. For something should that "must have contract" supposed to be good ;-) Thx & Bye Tom
  13. Servus Lennart, jep it works this way and it helps a lot because now is a reinstall of Retrospect no longer necessary. ;-) Thx & Bye Tom
  14. Hi Community, is it possible to run a script (Windows batchfile for example) before and after Retrospect run its own backup scripts? The reason why we need that is because we have a workstation with a database installed where no backup agent like for a Windows SQL server is available. So we would need to stop the database, backup the volume and start the database after Retrospect finished the backup. Thx in advance & Bye Tom
  15. Servus Lennart, the pre/post script finaly should run on a client machine. Maybe I should work with Windows backup wbadmin on that kind of machines, this is fully scriptable. Thx & Bye Tom
  16. Servus Lennart, > There is a built-in scheduler in Windows I'm aware of the Windows task scheduler but this isn't what I want because without a trigger from Retrospect when the backup is done I have to take care on myself that the Windows script doesn't start the database service to early for example. It could be possible that the Retrospect script starts not on the scheduled because any reason (waiting for the client or the backupset for example) an than I run into trouble because the Windows task scheduler has no knowledge about that delay... Thx & Bye Tom
  17. Hi Comunity, what is the best way to move a folder, which contains the content of a backup set (*.rdb), to another partition? Just cut & paste and reselect the destination in the properties of the backup set or rebuild the catalog file using the "new" destination or however? Thx & Bye Tom
  18. Servus Lennart, that's the way it works, thanks a lot :-) Bye Tom
  19. Hi Community, since we noticed that we cannot restore a single SQL database from a differential backup when the complete SQL server was backuped, because problems with the master db in connection with differential backups, we try to backup only the DBs we need but we cannot select single DBs in the SQL backup agent, only the complete SQL server is available. See attached png. What we have we missed? Thx & Bye Tom
  20. Hi forum, we try to restore a single SQL database (based on Microsoft SQL server 2008) but if we select a differential backup, Retrospect tells us that it isn't able to restore from that source, -> "select another source". If we select the latest full backup it works as expected. The checbox "Restore any needed intermediate Snapshots" is activated. We discover a problem during the differential backup, Retrospect logs the error that only full backups of the master database is possible. We don't know if there is a connection? Does anyone know what's going wrong? Thx & Bye
  21. Servus Antti does it mean, that I can't backup the SQL Server on the whole, if a differential backup from another database than the master db is needed? Otherwiese does it mean that I can only backup single databases if differential backups are needed? It seems that the differential backups from the other databases than the master db are broken also. Thx & Bye Tom
  22. Hi Community, in an Exchange 2010 SP3 (w2K8R2SP1) Server we get each time an Exchange DB backup is running a number of times the error event id 6 MSExchange CmdletLogs in the MSExchange Management section. Microsoft means that normally the admin can ignore these messages because generally this is caused by typing errors. But this is not a hand writen command in a power shell but a command invoked from Retrospect. Does anybody know how we get rid of these errors? Thx & Bye Tom
  23. Hi Community, what is best practise to exclude Retrospect files for scanning by AntiVirus product? Now we exclude all RBC files (Cataloug) and all RDB files. By default are also LOG files excluded. Is there anything else to exclude? Thx & Bye Tom
  24. One day we took notice that our anti virus (Trend Micro) found malware in a disk backup set of one of our file servers. So we think that the Retrospect RDB files are nothing but archiv files which an anti virus tool can take a look inside, like ZIP archives. So our thought is that this maybe can happen also to an Exchange server database stored in an EDB file for example and afterwards it could be possible that the database is corrupt and we run into trouble when restoring such an manipulate database. So we decided that the backup should be as it is and no third party tool should manipulate the backup files. That is our intention... Thx & Bye Tom
