We're on a retrospect and I guess they're going away. We need to find a new back up system.
Any suggestion?
thanks
For Data of our server we use Winrar. RAR backups may be opened or created with Windows, Mac, or Linux.
The program is inexpensive and available as shareware fromwww.Rarlabs.com, a powerful tool to process RAR and ZIP file , advantages are numerous
1. Unlike a dedicated backup program this can be installed anywhere.
2.Advantage of using a program like this instead of a straight copy program aside from obvious compression advantages of 40 or 50 % is if you should copy to DVD or BlueRay a file with a regular copy program it will normally become read only - this creates a big job if you then restore a database back to original location as you might have a mix of files with some requiring Read Only attributes and that should not be read only.
3. This program is also able to store extra file check information so if a portion of the disk is damaged the data may still be read. You can specify 1% and higher of authentication info - yes it costs space but greatly increases chance of restore should you have a sector error - this used to be more applicable to floppy drives but may still be applicable today with dvd's or bluerays, - I can't say - mine always restore due to above, though I do use multiple redundant backups so I am not limited to 1 chance at a restore.
4. Program is able to backup across multiple disks - more to the point if you don't have your hard disks formatted to a file system like NTFS but instead to a low common denominator like FAT32 you are limited to a few gigs max file size, this program creates multiple files that can read back together into 1 large system.
5. Program has Graphical Interface but also a command line interface so you may create Even Day, Odd day, week or month batch backups. If you choose you can then use a timer on your operating system to institute an automated backup or simply double click the batch file at night for appropriate backup.
6. Program has command switches allowing you to backup open files - Obviously you must use discretion here as the open files when saved later could incorporate additional changes making your backup incorrect. An example of use though would be if you have a DBAse relational database left open at night, a normal copy backup would miss all open files so your Database program would no longer read it if you restored a normal copy backup. If you used the Winrar backup (with switch set to read open files)the files would have been read and the database should thus be able to be opened - abeit in the state it was when saved by Winrar.
7. All above benefits are useful to backup hard disks not just DVD or BlueRay or USB thumb drives.
The above is for Data files - it is not a SQL database backup, my understanding for that is normally there is a way with a SQL database to save a regular text type file as a backup and that file would then be saved .

For backup of Workstations I suggest a Ghost Cloning type backup - for 512 megs RAM systems or above
Redo Backup Bare Metal Restore Solution GUI Backup Open Source GPL Recovery for lower RAM systems or for Cloning from 1 drive to another
Clonezilla - About .
Caution Redo backup and Clonezilla systems are great for ordinary file systems, they suck big time on things like mirrored linux drives (I have no experience using them with mirrored ntfs drives) as they slow down to a bit for bit copy and take forever. - for those situations I use the Winrar type data backup and expect to restore the operating system from operating disks if disaster takes out the mirrored drives.
