Disk Restore FAILURE - "Index Corrupted"
DISK RESTORE FAILED - "Index Corrupted":
For years I've had great luck using Acronis TI to create and restore Disk images. But a recent restore failure of a disk image made last night has shaken my confidence in using Acronis to secure my data, etc.
The disk restore failure was accompanied by the message "Index Corrupted".
THE FAILURE: I got a windows Blue Screen of Death (win 8.1), so I decided to restore the previous night's disk image backup using Acronis Bootable Media (from ATI 2017, 8058). It should have been easy - I was just trying to restore the previous nights backup. I've done it many times. But the restore failed, saying "index corrupted". And every attempted restore of the past three weeks of nightly disk backups all failed, and all for the same reason - "index corrupted". (3 version chains, 1 wk each - so 21 nights of backups).
I was able to succesfully restore a backup made months ago (using Bootable Media), so at least I can get the machine running - but that backup is too old to be of practical use. I need to be able to restore one of the nightly backups from the past 3 weeks.
MY NORMAL BACKUP ROUTINE: I backup nightly. Acronis 2017, v8058. I backup my main disk (ie all partitions), and save the backups onto a separate disk. (Backup Scheme: Custom Incremental, keeing 3 weekly chains equaling 21 days of backups.) All backups verify, both immediately after they were created and now.)
MY CONCERN: First, I want to be able to restore my most recent disk image. But more importantly, I'm now worried that my Acronis backups are not reliable. If a verified backup made the night before can't be restored, wow, that raises serious questions about the reliability of all existing backups.
"INDEX CORRUPTED" MESSAGE: From what I've been able to gather, the "Index Corrupted" message may be related to a corruption that existed on the ssd when the backup was made. Is that correct? If so, I'm wondering how Acronis went at least 21 nights worth of backups without warning me that there was going to be a problem restoring "index corrupted" backups?
WHAT NEXT? Is there is anything I can do to restore the Disk backup. (I am able to restore individual files, but that doesn't help me). Again, I'm using Acronis 2017.
For example, is it possible, using another machine, to mount the corrupted backup, then use chkdsk to fix it, then restore? (I've seen talk of this working on ATI 2014, but not more recent versions.)
Again, this whole incident has me very shaken. I had grown to trust Acronis's backups. But discovering that 21 days worth of "verified" backups can't be restored is a huge confidence buster.
(BTW: can someone at least tell me if Acronis latest version, 2019, would have prevented this fiasco, perhaps with an advance warning about "index corrupted" problems... BEFORE it's too late, ie before a restore is attempted.)
Any help is appreciated.
