Extract text from Split backup files (SN1)
To convert SN1 Backup files to another format, you need Acronis True Image or other Backup software.
To convert other file formats to the "Disk Backup Image" file type, you need software like Acronis True Image or a similar tool.
The .SN1 file is primarily a disk image backup or a backup continuation archive. Users create these files to store a sector-by-sector copy of a hard drive, system partition, or complete operating system environment. IT professionals and home users rely on these files for disaster recovery, system migrations, and full bare-metal restores.
These files are generated and managed by commercial backup software suites, most notably Acronis True Image (now Acronis Cyber Protect) and StorageCraft ShadowProtect. In specific scenarios involving Tom Ehlert's Drive Snapshot utility, the .SN1 file functions as the first continuation volume of a split backup archive, directly following the primary SNA file.
Users often need to convert or extract these files to recover individual documents without executing a full system restore. However, the .SN1 format presents significant disadvantages. It is a strictly proprietary, undocumented format that utilizes aggressive compression and proprietary encryption. Files frequently exceed 100MB and often reach several terabytes. The format locks you into a specific vendor ecosystem, often requiring an active subscription or an outdated software license simply to access your own archived data.
The most practical conversion targets involve extracting the contents to standard virtual disk formats like VHD, VMDK, or raw ISO files. Alternatively, users want to extract standard individual files like DOCX or JPG. Converting an .SN1 to an open standard often strips away vendor-specific metadata, incremental tracking history, and custom compression efficiencies.
This file format is exceptionally difficult to open or convert. Because it is a closed, proprietary format, standard online converters fail to process it. Often, only the original software can properly read, mount, or export the data. Just drag and drop your file to identify the format, view it, and convert it when possible. convert.guru can still identify the file format, inspect the file, and show text or internal content. If our analysis detects a supported underlying or embedded format, viewing or conversion may still be possible.
Convert.Guru analyzes your SN1 file, detects the exact format, and lets you read the text inside.
Users also converted SN2, SN4 and SN5 files.
If you want to convert SN1 file to BAK, BACKUP, OLD, TMP, TEMP, ARC, ZIP, TAR, GZ, 7Z, RAR or ISO, you can use Acronis True Image or similar software from the "Disk Image Backup Storage" category. In the File menu, look for Save As… or Export….
To convert SNAPSHOT, OLD, IMG, RESTORE, ISO, COPY, VMDK, TMP, VHD, BAK, ARCHIVE or BACKUP files to SN1, try Acronis True Image or another comparable tool in the "Disk Image Backup Storage" category.
The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our SN1 converter.
