Hello Erwann I admit I am quite lost .....
I run a regular incremental backup on disk F: (first time , so like full backup) As: INC F: -su=yes I run a full image backup of F: as: backup image F: But if I run after a backup image with -mode=incremental got error: tsm> backup image f: -mode=incremental ANS1813E Image Backup processing of '\\nasw\f$' finished with failures. ANS1229E MODE=INCREMENTAL is not valid on \\?\GLOBALROOT\Device\HarddiskVolumeShadowCopy17. Image backup not processed. I erased everything an made a test without doing a regular incremental backup of disk F as shown below: tsm> backup image F: Image backup of volume 'F:' Total number of objects inspected: 1 Total number of objects backed up: 1 Total number of objects updated: 0 Total number of objects rebound: 0 Total number of objects deleted: 0 Total number of objects expired: 0 Total number of objects failed: 0 Total number of objects encrypted: 0 Total number of objects grew: 0 Total number of retries: 0 Total number of bytes inspected: 19.99 GB Total number of bytes transferred: 86.41 MB Data transfer time: 4.00 sec Network data transfer rate: 22,123.01 KB/sec Aggregate data transfer rate: 13,869.33 KB/sec Objects compressed by: 0% Total data reduction ratio: 99.58% Elapsed processing time: 00:00:06 tsm> backup image F: -mode=incremental Total number of objects inspected: 16 Total number of objects backed up: 0 Total number of objects updated: 0 Total number of objects rebound: 0 Total number of objects deleted: 0 Total number of objects expired: 0 Total number of objects failed: 0 Total number of objects encrypted: 0 Total number of objects grew: 0 Total number of retries: 0 Total number of bytes inspected: 41.56 KB Total number of bytes transferred: 0 B Data transfer time: 0.00 sec Network data transfer rate: 0.00 KB/sec Aggregate data transfer rate: 0.00 KB/sec Objects compressed by: 0% Total data reduction ratio: 100.00% Elapsed processing time: 00:00:06 tsm> Of course NO data in the -mode=incremental but NO error ???? What is the correct sequence to have combination of regular incremental backup and iimage backup ??

The -mode=incremental flag uses incremental by date method that does not, so TSM DB is not aware of file deletion. -- Best regards / Cordialement / مع تحياتي Erwann SIMON ----- Mail original ----- De: "Robert Ouzen" <[email protected]> À: [email protected] Envoyé: Lundi 15 Juin 2015 14:50:58 Objet: Re: [ADSM-L] Backup and restore question Hello Erwann I need a little bit more explanations. if I understand correctly ,I need to do; 1. backup image E: (full backup) 2. backup image E: -mode=incremental (only new files are backup , fast backup I want to use (test) the restore with option imagetofile Restore image E: F:\diskE.iso -imagetofile -incremental –deletefiles So NO need for regular incremental backup ???

When specifiying mode=incremental, il a file level incremental that is done : only files having a modified date later than the previous backup image are backed up. The -deletefiles flag when restoring an image backup is only to be used when backup of the same volume is done twice : block level (image backup) and file level (regular forever incremental). See this excellent presentation (from slide 28) : http://tsm-symposium.oucs.ox.ac.uk/2007/papers/Andy%20Raibeck%20-%20Potpourri%20du%20Backup.pdf -- Best regards / Cordialement / مع تحياتي Erwann SIMON ----- Mail original ----- De: "Robert Ouzen" <[email protected]> À: [email protected] Envoyé: Dimanche 14 Juin 2015 04:47:33 Objet: [ADSM-L] Backup and restore question Hi to all Question for people using BACKUP AND RESTORE IMAGE I have a Windows client with millions of files and I am thinking of using backup image on it. Some questions , after the first backup image of disk E: (full Image) as : backup image E: In the documentation I can use after it and incremental backup image as: backup image E: -mode=incremental CORRECT ? Of course the content of disk E: will change, files will be added and deleted. So the correct syntax for restoring the image will be: Restore image E: X: -incremental –deletefiles Any advice will be appreciate Best Regards Robert Ouzen Haifa University
